box

A small box 40mm wide 70mm long 24mm high.
I made it for mounting stepUpDown power pcb's. Comes in very handy for oll sort of atmega solutions.
I made one shell specifific for mounting a voltage display (23mm x 10mmxheight).
Panels with holes for wires/cable or plain to close the box.

Print a bottom and a top part with 2 panels and click it together.

Customize if you like by opening the freecad file and modifying a part.
To get seperate stl for your newly created part select only the part you want and export it to stl-file. Create a new freecad file next to the opened file and copy/paste a part from the original file into your new file. To copy or paste you must make sure the source or target file is the active file (dblclick on the filename in de document tree).
