A C Battery holder wall mount. Printed using 0.2mm layers, 0.4mm nozzle. Fits within a 220x220mm bed.

First 3D model I made myself. Sometimes the lower bezels on the main block string a little, and some supports help that. Could just be my printing settings as well, but it comes out pretty good. Comes in 3 versions, all with mounting holes sized for #6 screws. 

Constructive criticism is always welcome!

v1: 6 slots for C batteries, mounting holes are for #6 screws, no countersink on the mounting holes. 

v2: 6 slots for C batteries, mounting holes are for #6 screws, countersink on the mounting holes. 

v3: 8 slots for C batteries, mounting holes are for #6 screws, countersink on the mounting holes.
