Bob Cassette Rewinder Case

This is a case for the Bob Cassette Rewinder (https://github.com/dekuNukem/bob_cassette_rewinder). The original case by telekineticyeti (https://www.thingiverse.com/thing:4840829) didn't quite fit my rewinder board and also felt a bit thin, so i designed a more sturdy and compact one. It does not have the alignment helper, but i guess you'll know how to properly use the rewinder either way.
