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. :)

Wisconsin Hackerspaces / Makerspaces

Wisconsin Hackerspaces / Makerspaces

Just over a year ago, I don’t think I could have created this map… but here’s the current list of hackerspaces/makerspaces (that I know of) in Wisconsin. Some are well established, and some are just getting started. Either way, if you’re looking for a group of people and/or a space to hack/make things, here’s a guide.

I’ll start in Milwaukee, where we have both Milwaukee Makerspace and Bucketworks…

Bucketworks has been around (in various locations) since 2002 and besides being the venue for BarCampMilwaukee for the past 6 years, it’s also a great place for co-working, meetups, hackathons or other creativity-related activities.

The Milwaukee Makerspace as a group has been around for about two years, but just got their space less than a year ago. In that time they’ve managed to build up membership and acquire quite a list of impressive equipment. If you’re into physical making of things in the areas of electronics, robotics, woodworking, metalworking, 3D printing, electric vehicles or any sort of building/making, it’s an awesome place filled with smart people.

Over in Madison we’ve got Sector67, which is more of a “community workshop” where pretty much anyone can come in off the street and work on a project. If you want to be a member, you’ll help keep the place alive, and gain other privileges, but if you just need help on a project, show up and see what happens. They’ve also got some private space set aside as a small-business incubator.

Up in Appleton we’ve got a group known as The DHMN (which stands for “Distributed Hacker/Maker Network”) The DHMN doesn’t have an actual space yet, but they’ve got some dedicated and enthusiastic members who meet regularly and are slowing building up members so they can someday have a permanent space.

MakeBit is just a bit south of Appleton in Fond du Lac. I don’t know a whole lot about MakeBit, but Tim Bertram is the guy behind it, and hopefully he can make it happen get a space at some point. (Right now it seems they are just gathering interest, which is definitely the right way to do it.)

A bit north of Milwaukee and Madison (and about the same distance from each) is the Beaver Dam Makerspace. Hacker/Maker Jason Gullickson is the guy behind this space. I say “space” because it appears they do have a space thanks to some solid connections in the city, but they’re still finding people interested in being members. I’m hoping we see some action here in 2012.

The newest group/space I’ve heard about is the Wausau Collaboration Center. The folks behind it seem pretty focused on making it happen, and seem to be following along the lines of Sector67’s “community workshop” idea. This isn’t surprising, as many of the people involved in these groups/spaces have met each other, know each other, or someone influence each other. (That’s probably a good thing!)

Oh, there’s a few more spaces mentioned on hackerspaces.org but the domains seem to be gone and I’ve never heard of them.

And if I missed any, let me know! I’d like to eventually visit them all, meet the people behind them, and maybe even get stamped.

BarCampMilwaukee6 Happened…

I survived BarCampMilwaukee6… just barely. (Maybe that’s what the t-shirt should say.)

Somehow I did what I never did before, and that was: stay awake from the beginning to the end. And yes, as the old saying goes, I’m getting too old for this shit. Next year, someone point me to this post and tell me I should sleep a few hours.

OK, on to the recap… How did things go? They went great. In fact, I still can’t figure out if all that time I spent freaking out about things not getting done was necessary or not. I mean, there were a few hiccups, but much of BarCamp really is self-organizing, but only after the event starts. There is still a lot of prep work to be done in the weeks (months?) before BarCamp. Wrangling sponsors is one of the big ones, and I’d really, really, really like someone else to jump in next year. I have some ideas, and I would love to advise on it, but I need some help. That said, I’m really proud of the fact that we tend to have mostly smaller, community-owned organizations as sponsors. We don’t have large, faceless corporations throwing tons of money at us (should we?) but we’ve got people who come every year, and see the value, and have their company (often one-person shops) toss some money our way. It’s pretty damn grassroots if you ask me. And if you feel like sending more money our way, please, please just send it to Bucketworks. They’ve hosted us for 6 years, and really don’t get much out of it from a monetary standpoint. Help support what AccordionGuy called “the best venue ever for a BarCamp.”

As for the “self-organizing” part, once people are at BarCamp, and see what it is, and see what is needed, they step up and do what needs to be done. It’s that whole “doing things ahead of time” thing that is tough. How do we get more people involved in the planning? I don’t know… was Atrium really what prevented people from voicing their opinion? Do we need to return to a Google Group to get people to volunteer for things? (Of course, some folks hate that tool too… you can’t please everyone, right?)

Well this post has turned into a jumble. I’m sure I’ll have plenty more to post about, but for me the highlights were the “3D Printing Village” in the Workshop. That’s where we stayed up all night printing crazy stuff. (Yes, there will be video.) Besides that, the Lightning Talks were fun, and I learned a lot about silicone mold making, met some new folks, got to see old friends, and generally had a good time.

Another great thing was all the makers who showed up, not just from Milwaukee Makerspace, but also from Pumping Station: One, and Twin Cities Maker. It was awesome to hear someone say it was well worth a 6 hour drive to attend, and that they’ll be back next year.

We also had a ton of new people. First time Campers! I thought this was great to see… not just because I want more people to come to BarCamp and get excited about it, but because I remember what it was like before I found a tech community in Milwaukee, and how great it is to find a place/group/event where you fit in, and feel like you’ve found your tribe. Welcome new people! We hope to see you next year. :)

Posting Elsewhere…

Good Friday everyone! I’ve been busy writing and making things and writing, and I also have a backlog of ideas to write about…

But I just wanted to mention something for the folks out there who enjoy reading my writing (both of you!) and let you know that you can also read my writing elsewhere.

VerveCast

I post over on the VerveCast blog, which is published by Z2 Marketing. I usually post about once a week. You can certainly just see my posts, but I’d encourage you to check out the other authors as well. We’re a branding firm, but I often delve off into subjects like 3D printers, desktop manufacturing(?), experts, and weird photos.

Milwaukee Makerspace Since those guys (and girls!) at the Milwaukee Makerspace were kind enough to let me join and hang out there, I’ve also started blogging over there. I often post about my own weird projects, but I also try to post about interesting topics, demos we do, or just a typical night of hacking and making.

And if all that isn’t enough (and it should be!) you can occasionally see mysterious images over on Posterous, or see the strange things I post on Google+.
