I'm printing a new version of my round robot chassis with PETG. I had one initial objective: to add better battery enclosures, because the batteries on the first one just fell out. So I added some integral ones. I looked around Thingiverse and found these , which led back to these . I actually designed my own: since I needed to resize to CR123, and didn't find the SCAD files all that readable: full of magic numbers... I used the clips from the second design, because they were better specified, and not expensive from rs-components. Anyway, I printed that version in PETG. When I came to get it off the plate, the base layer just stayed on the plate: the adhesion between the plate and the base was greater than the adhesion between the shell and the filling! I've refactored the chassis quite a lot to deal with that. The latest iteration is printing now. The other change was to support a Nucleo 64 board like the STM32F303RE one. I've managed to remove the programmer,

I found this Raspberry Pi Zero camera enclosure on Thingiverse. I printed it first using Cura to slice it. That didn't work so well: every 5mm or so, the model had weak layers. I decided it was time to try slic3r instead. Slic3r is much better supported by Prusa Research: you can get a config bundle from the Mac distribution , and I've just installed the Ubuntu version:   $ sudo apt-get install slic3r I was expecting a lower level experience to Cura, but basically it's the same interface: a view of the build plate with the objects on it, and some tabs to configure the options. I definitely won't bother with Cura again. The model itself might benefit from a bit of smoothing around the slots before you put it together. Don't use a nyloc nut in the pivot if you printed with PLA at least: it won't be strong enough. I found out the hard way, but of course I could just print another one. I'm now installing MotionEye as per these instructions . MotionE
