Case for a FiiO M3K music player

One of my kids has a FiiO M3K music player, and the silicone case that came with it was falling apart. We spent some quality time together with calipers, radius gauges, and FreeCAD to model a case. Then we had to wait a while because the printer capable of printing NinjaFlex was out of service, but now that it’s back in service, we printed it.

Blue NinjaFlex looks sparkly when printed at 250°, it seems! Blobbed a little, so I think there was slight over-extrusion, but it’s serviceable.

Requires Realthunder’s branch of FreeCAD for “Save as directory”

I’ve made some improvements from the print, but the print is good enough for us so we probably won’t print it again.
