Update 3/11/19: Added a cover for my Octopi RPi developed from this logo adaptation: https://www.thingiverse.com/thing:2805595
Making progress doing these in Fusion 360 but the Octopi one I did came out very ratty. Then, I was able to create a better .svg file by taking a snip .png of the logo cad file open in inkscape and just threw that into Tinkercad to get the final. This one used the eSun eSilk PLA in dark yellow.
I like this straight-forward, simple, snap case for Raspberry Pi's (https://www.thingiverse.com/thing:1572173) so I re-mixed the cover with my makerspace's logo (DecaturMakers.org) and then with the Bitcoin logo for the RPi I use for bitcoin mining. I used Tinkercad for design. Hmm, looks like I forgot to flip the DM logo over so it actually is reversed when it's on the Pi...oh, well, more work to do.
Solutech 1.75 PLA
Blue and White
The Decatur Makers' logo has some free floating elements, so I used little rectangles to bridge them.
