TB-406 Insoluables Tailings Tank

This is a project that's actually tied into my day-job.

One of my projects at work is to replace a steel tank at a mining facility. I worked with one of our staff designers on the tank drawings, and the project manager, who had seen my printer during the "Bring Your Kids To Work Day" commissioned me to print it.

The designer was able to export the model from AutoDesk as a .stl. I printed a prototype as a solid model, but did not really like how it turned out. Several of the connections were too small, and the top layers didn't print well on top of the 10% infill I specified.

I printed the final version in two parts. I used TinkerCAD to separate the roof plate from the rest of the vessel, and printed the main body with 0% infill and 0 top layers. I spent a couple hours editing the model of the top plate to make everything thick enough to print, mostly by changing I beams into solid rectangles.

Overall, I think it turned out pretty well:

My Project Manager was very pleased!

Incidentally, this is a 25.4:1 scale model of the real tank. That's because the original model was in inches, and my printing software defaults to millimeters!

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:

Dry Erase Marker Holder

I remixed a design on Thingiverse to make this:

First time I have remixed a design like that.
