omni-wheel-01

I was at a robotics event a while back and saw so many omni wheels I got inspired to try to design one. I remember looking up omni wheels years ago and seeing how expensive they were, so 3D printing my own seemed like an obvious choice.

omni-wheel-model-01

I mostly succeeded in designing and making one, but it’s also quite a bit of a failure. Don’t get me wrong, it was a fun exercise, and I tend to enjoy a design challenge, but these aren’t gonna work.

omni-wheel-03

I had planned on brushing Plasti Dip onto the wheels to give them some grip, or maybe casting them from Silicone. (Someone else suggested printing with TPU filament.) If I get back to this project I might consider some of those ideas…

omni-wheel-model-02

So where was my big mistake? When I modeled this, I did not model in the hardware. Sure, I modeled in the holes for the hardware, and what I thought was enough space for the heads of the bolts, but the bolts stick out just a bit too much. As I said, this was a fun exercise, and maybe I’ll revisit it in the future but…

omni-wheel-02

I went looking for omni wheels again and found this VEX IQ 63mm Omni Wheels (2pk) for about $10, which means for $20 I got 4 really nice omni wheels. They might also serve as a reference if I try redesigning my wheels, now that I have a good example to go from. Maybe my choice of 3mm hardware was a poor one. Hmmm, I’m already thinking about the next iteration.

mms-collateral-4934

Billy, one of the new Board Members at Milwaukee Makerspace, was interested in having some letterhead made up so he could solicit donations in a more professional manner, so I designed a letterhead and also made up new cards while I was at it.

mms-collateral-4923

In case you didn’t know, I actually have a degree in Graphic Design. I don’t do a lot of “classic” graphic design for print, and most of my design work nowadays is in developing products and projects and physical things. Still, it was fun to do a little design work.

card-generic

Here’s the front of our “generic” card which we hand out to anyone, at events, etc. Basic info about the space. I brought back our old “Conceive, Collaborate, Create!” motto. (Weird spacing at the top is due to issues.)

card-back

On the back I added the part about being open on Tuesdays. Telling people to come on a Tuesday at 7pm is the most common thing I say.

card-pete

Each member of the Board of Directors also got a card designed. They could choose if they wanted their phone number on it. (Not all members wanted cards.)

letterhead

The letterhead itself has a clean look, and a line that says “Milwaukee’s Hackerspace and Fabrication Lab” which is also found on the web site and a call back to the early years of describing ourselves.

Since this is a makerspace (or hackerspace) at least one member had to argue about the cost of having letterhead made. We pointed out that the cost of letterhead was a fraction of the amount of money Billy had already saved us by soliciting donations and getting us cheaper services from our waste collection company and Internet service provider. (Some people just like to argue.)

mms-collateral-4931

We got the printing done using one of those “cheap” online services where you upload your files and then show you a preview and you hope it’ll all work out. Things are not 100% perfect. The cut lines and bleed were not totally right, but they’re good enough for our purposes. (Spacing on the letterhead is much better than the cards, but again, we’ll survive.)

mms-collateral-4904

Big thanks to Billy for pushing me to get this done, so he can do more awesome things for Milwaukee Makerspace.

green-button-box

I tend to make objects. Things. Pieces. Sometimes I think I can apply the word “sculpture” to them, mainly because sometimes there isn’t a better word to describe them (especially if they are to be considered “art”.)

Many of the things I make are “functional” in that they do a thing. But what is that thing? What does it mean to do a thing? They might make something happen, or move, or light up. The might be kinetic or reactive or interactive. They may solve a problem. They may make the world a better place. They might look pleasing.

And then there’s jewelry…

I’ve had a strange relationship with jewelry. I never really cared for jewelry. Beyond the relationship humans have with jewelry, and how it fits into society, I just never really cared about making jewelry. I think that some art instructors use jewelry making as a way to teach process and making, and maybe use it because many (most?) people like it and would like to have jewelry, or maybe because it’s such a personal thing. I mean, it’s work on the body. That’s personal, right?

ring-vise

I even ended up making a piece of jewelry for a class titled “Machines that Make”. I designed a hammer ring. I learned a bit more about Rhino, and I got a print made by Shapeways, which was a good experience, but as far as a piece of jewelry, I didn’t care about it. (I mean, It’s an interesting object, but I’m not going to wear it. Like many of the things I make, there’s humor somewhere deep inside of it. Or maybe on the surface. I don’t know, I’m still figuring this out.)

Much of my art & design background involved 2D work, which, let’s be honest, often hangs on a wall, or is just seen and doesn’t do a thing. But doesn’t it do a thing? Does it provoke thought or emotions? Does it instruct or inform? Does it make you feel something? Does it make you happy? Things do things.

I remember back in a high school art class we had to make a ring. I had zero interest in wearing a ring or making a ring, and I really dragged on the project. I think I eventually finished it (late) and I don’t even know what happened to it. It was a piece I just didn’t care about. I probably could have learned about etching metal, and creating different kinds of resists, but I just wasn’t invested. (I know, this is all a person thing.)

My daughter has started to make jewelry. I’m excited about it. Not because I like jewelry, but because she likes jewelry. Or, maybe she just likes making things. It seems therapeutic. She’s mostly doing wire wrapped jewelry. I use wire for electronics and for securing things. Making jewelry with it? I guess some people do that.

ring-mads

She also learned how to do metal casting, which is awesome. I know a little about metal casting, and it’s something I wish I knew more about (but there are only so many hours in the day.) I’m glad she has the opportunity to learn it.

Also, Daleks…

What? Daleks? Yeah, well, Jon H. at Milwaukee Makerspace is the Jewelry Area Champion, and besides helping people make Daleks, helps people make jewelry. Or, learn how to make jewelry. Jon is an interesting guy. I’ve heard him called a “Retired Magician” though maybe he still is a magician! He’s got a lot of skills and is willing to share them. So yeah, sometimes you see Dalek parts being made in the jewelry area, because, the process is similar, sort of. Right? I don’t know…

Where is all this going? I’m really not sure. As I said, I’ve had a complicated relationship with jewelry. I don’t wear it, I’m not a big fan. It’s a personal thing. I don’t really like drawing attention to myself. I mean, my self. My physical being. I don’t mind using words to make myself known, or sharing my work, but I don’t want the focus on my physical body. That’s just how I am. I’m weird. Maybe. I don’t know.

dalek-jewelry

Well that turned into a rambling mess about art and objects and jewelry that I wasn’t fully expecting. Writing can be like that sometimes… What do you think?

Stand

I recently had to design a simple cabinet to serve as a stand for a mill/lathe. I thought about pulling out some rulers and triangles (yes, I used to actually do drafting with pencils and paper) but instead I decided to try using OpenSCAD.

Stand

I used specific colors in my design, of course when you actually render a thing in OpenSCAD the color goes away, but you can export the different views just fine without rendering. Here are the various view of the thing. Oh, since OpenSCAD is a “unit-less” thing which mostly outputs in millimeters (at least for STL files) I just assumed the units were inches.

Stand

I used the OpenSCAD “scale” feature to scale up the thing by 25.4 times in each direction, which means my 1 millimeter became 1 inch.

Stand

But in a real drawing you plan to hand to someone you need dimensions for things. While there’s been some experimentation in adding them, there just doesn’t seem to be an easy way to show dimensions of things in OpenSCAD. I resorted to printing out paper and marking it up… with a pencil.

Stand

I probably need to learn how to use FreeCAD for this sort of thing. I’m sure I can easily add dimensions with it. One of the really interesting things about FreeCAD is that it has an OpenSCAD Module. You can import a CSG file which you’ve exported from OpenSCAD, and you can just open .scad files as well.

Much more to explore here… stay tuned!

Adjustable Rectangular Mount v1

I finally got around to creating a parametric version of the 3D printed mount I’ve been using for the past few years. Typically I’d just open a previously designed thing in OpenSCAD, make some adjustments, and export an STL to print. Eventually I realized that I should just create a bunch of variables so I can easily just make minor adjustments each time and not have to do a bunch of find & replace operations.

The result is Adjustable Rectangular Mount v1 which you can find on Thingiverse and Youmagine.

It’s a work in progress, and it still needs some tweaking, but I figured it was worth releasing to the world. (Hey, make it better if you can!) It doesn’t work for all sizes and configurations, but for most of my needs, it’s good enough.

Adjustable Rectangular Mount v1

I should probably do more research on how to improve things by reading through other OpenSCAD code, but as mentioned, you’ve gotta start somewhere. I’ll probably be using this one quite a bit in the future, and I’ll update it as I can.

This mount specifically expects that you can use screws (or bolts) to mount it to a surface you can screw into or drill through. I also often add some double-sided foam tape to the inside of the mount and stick it directly to the object being mounted.
