This is a very crude and simple design meant to hold additional head sets for the DSPIAE reciprocating electric sander tool. The case the tool comes with has space for the initial 8 heads, but as someone who uses multiple grits in each project, I ordered extra sets of the heads and had nowhere to put them!
User Magomat32 had a good concept, but didn't make the file usable to anyone who didn't have a Prusa machine, so I tried my best to replicate the functional aspect of it, while also making it more compressed and use less plastic. They fit snug, so you may need to enlarge slightly if your machine isn't very accurate.
I encourage anyone who has a better handle on design to make a more pleasing or functional version; I'm a sculptor with no real understanding of design philosophy or CAD. I've included my blend file as well as a single holder for anyone who wants to try and iterate.
The author remixed this model.
I eyeballed and traced the inner perimeter of the head holder and used only that in order to create a holder that
1 - could actually be downloaded (Magomat32 only provided a useless prusa gcode file that my slicer could not read)
2 - uses a lot less plastic
3 - has different configurations
