Geared DC-Encoder-Motor enclosure for fischertechnik

Depending on the gear ratio, the length of your motor will vary, see dimension drawing. That's why I included versions for different reducer lengths.

Needs two M3 screws to fasten.

If you have a  motor without encoder, have a look at Arnoud's nice design over at thingiverse.
