Encasing for DC-motor (small type)

I needed a holder for my 6-14v DC-motor so I decided to make one. It's got 5mm holes for mounting in or on various places, and it has a lid.

This fits the following size DC-motor:

Diameter: 27,5mm
Height: 33mm

I've included a drawing file if you need to look closer at the measurements.


Feedback is very welcome, thanks!
