Hot Shoe Audio Mount

Since I’ve got the RepRap I can start on some projects I’ve been meaning to tackle, one of which is printing some camera accessories.

Hot Shoe Audio Mount

Thingiverse is full of weird combos of objects smashed together, such as the Lepus Colberus (The Colberabbit), but you can also combine individual objects in other ways.

I grabbed this 1/4-20 Thumb Screw and this Nikon DIY GPS Holder and combined them into a new thing.

Hot Shoe Audio Mount

The nice thing about the “Nikon DIY GPS Holder” I printed was that I can see it being a generic part I can modify in the future. I can easily import the STL file into Google Sketchup and built on top of it. (I did find this camera mount accessory, but the assembly was a little more complex than I wanted to deal with.) It did take a little bit of work with a file to get the part to fit the hot shoe on my Nikon, but that’s probably a good thing. I got it to fit just as snug as I wanted after minimal filing and sanding.

Hot Shoe Audio Mount

I’m still calling this one a prototype. I ended up drilling out the hole for the bolt, and I cut the head off the bolt to be able to make it all fit together. It works, but I can see some improvements for next time. (I’m also expecting better quality from the RepRap as I get better at calibrating and operating it.)

Hot Shoe Audio Mount

Here’s the mount on the hot shoe of my camera. I haven’t done a ton of video shooting with the Nikon D3200 yet, but I know that most DSLR microphones are not very good, and secondary audio is pretty standard, so by mounting the Zoom H2 on the camera I can get better audio, and I can also monitor the audio, which you can’t do with the Nikon D3200. (The Nikon D800 does allow you to monitor audio from the camera, but we still haven’t received ours.)

So besides two nuts and a bold, there’s probably 10 cents worth of plastic. I think this shows the power of 3D printing in making things you need. I wouldn’t have been able to make this out of wood or metal very easily, but a 3D printer and a hardware store made this a pretty trivial project.

Printed Chairs

Big Printer

Big Printer

Didn’t I say something last year about 3D printing being the future? Well, it is. There’s even a guy printing chairs from old scrap appliances.

Double-points for using recycled materials and a robot. (Lots more cool stuff at the Milan Furniture Fair as well!) Check the video below to see the awesome in action.

MakerBot Marketing

MakerBot Industries

I meant to write this post about a month ago, but writing it now just validates the points I was going to make anyway, so read on!

Back when I wrote 3D Printing is the Future, I mentioned a number of companies, including MakerGear, Ultimaker, and of course MakerBot Industries. Four months later, I’m going to update my thoughts on them, and specifically focus on what the MakerBot folks do in the area of marketing.

Wait… Marketing? If you read the piece in Fast Company you’d know that MakerBot Industries doesn’t do marketing:

… When I speak with MakerBot’s Keith Ozar, he seems offended when I refer to such undertakings as “marketing.” His background is in underground music promotion, and he joined MakerBot when the company advertised a “marketing experimenter” position in early 2011. MakerBot doesn’t really market at all, he counters; it actively participates in the community the company seeks to both cultivate and create, involving “people who are creative, people with imaginations.” That means a presence at Maker Faire-style events, where hardware hackers congregate, and more recently at comics conventions and the like.

Here’s where I haul out the disclaimer: I work at a marketing company. I also market myself, and the things I do. Almost everyone does, even if they don’t call it marketing. If MakerBot doesn’t want to call it “marketing” I’m fine with that, but let’s be honest, that’s what it is.

With that out of the way, let’s look at the marketing that MakerBot does…

MakerBot Web Site

MakerBot has a web site. Hmmm, that’s nothing special. Let me rephrase that: MakerBot has a good web site. Their web site clean, well designed, and organized. There’s a store, there’s info on the community, including links to User Groups, Twitter, Flickr, Google Groups, etc. as well as a link to Thingiverse. Their support page has a lot of links to their wiki, and then there’s the blog.

The MakerBot blog isn’t just some “look at me!” thing where they talk about themselves (though it has been a lot of that lately, due to the recently launched MakerBot Replicator.) The blog also highlights things that members of the community are doing/making. And the blog is updated very often. Very often. That’s key.

Ultimaker

When the Ultimaker came out I heard a lot of talk about how much better it was than the Thing-O-Matic, and it may be better, but take a look at the Ultimaker web site. It just looks like a blog, and as of my writing this, it’s been over a month since it’s been updated. And before that it was a month and a half. I know blogging takes time, but for a small company it can get you the most bang for your buck when trying to tell people about your product.

MakerGear

In the world of RepRap, reprap.org is packed full of information, but if you want to buy a RepRap kit, MakerGear is a pretty well known and respected seller of the Prusa Mendel kit. They also recently came out with the MakerGear Mosaic, which is their own design, and is a capable machine from all I’ve read.

Visit the MakerGear web site and let me know what gets your attention… if anything does. There is a “What’s New?” link on the home page, that links to a page with a post that was written nearly two months ago. (With a typo in the title.) I’m a MakerGear customer, and I think they’re a good company, but I wish things looked a bit more professional. For a first timer visiting their web site (or the Ultimaker site) I don’t think they’re going to be impressed.

But then, maybe these companies don’t want to impress people. Maybe they’re only targeting the alpha nerds, who know the inside scoop, and think that MakerBot is for people who don’t know better, and the real desire is for servicing a niche market. If that’s the case, then that’s fine… I honestly don’t know.

So besides the web site, what is the “MakerBot Marketing” you ask? I’ll just throw a few things out there.

MakerBot: has good photography, has good videos (including MakerBot TV), they have a curriculum for schools, are behind Thingiverse, they’ve implemented an Artist in Residence program, did the Project Shellter thing, scanned people’s heads, and on and on.

Some of those things take a bit of money, which smaller companies may not have, but there’s no shortage of clever ideas, some of which are relatively cheap, and if it gets people talking about you, isn’t that what you want?

So yeah, MakerBot Industries does marketing, and it may be marketing on their own terms, and in their own way, but in the end, if people find out about you, and keep hearing about you, that’s building your brand, and that’s worth a hell of a lot.

Here’s the thing: You can have the greatest product in the world, but if no one knows about it, you won’t have any customers, and no customers equals no business, so marketing is important… even for nerdy 3D printer companies.

(Oh, there’s one more thing that’s key to MakerBot’s marketing effort, which I’ll probably talk about in another post.)

Printrbot

Printrbot

You’ve heard me say that 3D Printing is the Future, and I’ve talked about the MakerBot, RepRap, and other 3D printers, but fairly recently, a new project called “Printrbot” launched, and more specifically, they launched on Kickstarter, where their goal was to raise $25,000 and when the campaign ended they raised $830,827. (3,323% funded!)

You could say there’s a lot of interest in 3D printing…

And 3D printing moves fast! I received a MakerGear RepRap Prusa Mendel about a month and a half ago, and I’m still building it.

When I say “I’m still building it” I should clarify that I only get at most a few hours each week. I’ve been told you can assemble the entire thing in a weekend if you skip meals and sleep. :)

But supposedly the Printrbot can be assembled in an afternoon. And it’s smaller, and lighter, and cheaper. All good things. I’ve heard a few questions as to the speed, print quality, etc. of the Printrbot, but I’m fairly confident it’s well designed and will be comparable to the other 3D printers in it’s price class (even though it’s probably the cheapest right now.)

At Milwaukee Makerspace we’ve got a member with a MakerBot Cupcake, I’m building a Prusa Mendel, and I’ve heard that one member backed the Printrbot project and should have one of those when they’re available.

Oh, I should also mention that a goal of the Printrbot is “a printer in every home (and school)” so right there, I’m a fan… and a backer.

If you’ve ever thought 3D printing was too expensive, keep an eye on the Printrbot project, and see what they can do to change your mind.

Simplfying STL Files with MeshLab

Cow (Sketchup)

So back when I first used the MakerBot at Milwaukee Makerspace, my daughter asked me to make her a cow. (The kid likes cows!) Since my 3D modeling skills were not up to the task (and still aren’t, at least not for a cow) I found a cow in the Google 3D Warehouse and brought it into Sketchup.

It looked fine, so I exported it as an STL file and did a print. A very small print. It looked OK (but not great) and since it was small there wasn’t really much detail.

Since then I’ve looked at other files in the Google 3D Warehouse, but since most of stuff there is for screen display and not 3D printing, things tend to be very complex, at least in the well done models. More complex than might be needed for a 3D print, at least from the Makerbot.

I’m still pretty new at this 3D modeling stuff, but simplifying the model seems to be what we want. In the 2D world I’ve been doing the same sort of thing for 20 years, but in 3D? It’s new ground.

Enter MeshLab!

From the MeshLab web site: “MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes. The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.”

I’m mainly interested in using it to reduce the complexity of 3D models.

Cow Original (MeshLab)

Here is the STL file I created from the original cow in Sketchup, as seen in MeshLab.

Cow Reduced (MeshLab)

Here is the same file after reducing the complexity using the Quadratic Edge Collapse Decimation filter. I still feel like it’s a bit of black magic figuring out exactly what numbers to use, and what checkboxes to check, but this is what I used for this one:

MeshLab Settings

I’m fairly pleased with the results (though I haven’t tried to print it yet) but now that I’ve got a (loose) handle on mesh reduction, I’ll dig into the tutorials on YouTube from MrPMeshLabTutorials, including this one on Decimation.

(Of course I still wish MeshLab had an Undo function.)

Oh, and if you really want to 3D print a cow, this recently added to Thingiverse cow is probably the one you want. :)
