Dremel Micro is a very nice little portable tool.

Unfortunately most of the bigger brothers add-ons are not compatible with Micro, so I've decided to build some for myself:

• a table saw
• a table grinder
• a drill stand adapter for Proxxon MB140/200

The design is modular (10 pieces), in order to use as small amount of filament as possible. You can just combine the modules or glue them (except the covers).
A short video with the add-ons:

Just print all 10 pieces in ABS. The assembly is highly intuitive.
