Raspberry Pi Cases

I've been customizing some raspberry pi cases for my home automation hobby, and they have gotten some nice feedback on Reddit and Thingiverse.

I started with someone else's design, then started removing features I didn't want:

Then I moved on to adding logos that I wanted. I found another design, and started hacking away at it. First up was an OpenHAB logo. It took a couple tries to get something I liked.

Once I had that model sorted, it was fairly easy to swap out logos, and I quickly added designs for HomeSeer:

And for HomeAssistant:

You can check out my designs on Thingiverse, if you like.

Human Nudt15 (MTH2) Protein Model

My sister-in-law discovered the structure of this protein during her research. I printed it out for her.

We were able to work together to follow this walk-through on converting the protein model into something I could print.

The protein is actually two halves that work together. I first printed a prototype of the whole thing in one piece:

Then I printed the two halves separately to see how well they fit together outside of a virtual model:

At that point, I knew they would fit together, and I knew roughly how big I needed to print them to get all the detail in with my printer's resolution.

However, I wanted to go fancy: I wanted the two pieces to magnetically snap together.

I modified the 3D file to have a gap for a magnet, then inserted the magnet at the last layer with the gap open, while the printer was still in operation:

The magnet was solidly in place in the final product. You can see another magnet hanging from the finished part here:

I then did the same procedure with the mating half:

Et Voila, they mated nicely!

But I wanted to go fancier still. I printed these in ABS so I could use Acetone Vapor Smoothing to really give these models a glossy sheen.

I bought an old slow cooker at my local Goodwill, and subjected both models to hot acetone vapor for about 10 minutes.

They came out looking pretty slick!

Holographic Cortana Appliance

I just saw this really cool project.

I'm gonna build one.

It might take me a year.

Venus Box

Here's a clever little design. It prints as six pieces that are assembled later:

Prints for Coworkers

I printed off a few things for some coworkers:

All printed in PETG. There was ZERO warping on that big flat bottom of that last one. I'm very poud of that.

Dry Erase Marker Holder

I remixed a design on Thingiverse to make this:

First time I have remixed a design like that.

Charizard - More PETG

Man, I'm liking this PETG. There's a fair amount of stringing, but you can actually bend and flex those wings!
