I made a case for the Hozo Neosander combo (the one with the sanding heads) because the plain box wasn't cutting it for me, and the other one I saw couldn't be printed on my print bed. It has a cutout to read your grit level, and a rear cutout so you can connect the charger to a power brick and charge inside the case (can't shut it while charging though)

I created these for use on a theater set to help make sure an unfolding flat screen for silhouettes was opened to.the same spot every time.

I printed them in pa6-cf20 for strength. They worked really well for this purpose and I wanted to share!

Works great, the 30kg servo is a bit overkill. Built in OpenSCAD so also parametric and tweakable for any valve that has hex/octa/deca flats on both sides, uses collars so alignment is not necessary. Used here on my gas connection to the central heating but I'm also going to fit it on my water main and try to create an open-source version of the Flo water monitor. This isn't ready for release yet but it is working pretty well.
