I have Dremel like cordless rotary tool from Parkside that comes in nice packaging but very unpractical. It is hard to get main tool out of the box or put it back. And if like me you have additionall accessories this multiplies number of boxes required to use a tool. So I have made my own box set. It is modular and you can decide which parts you need.
This model is less then 6 cm diamiter and 20 cm height. I do not know what about other tools. So make sure it fits or modify included dource files.
I ma including souce file in FreeCAD format and step files so it should be easy to modyfi the project. And the model is parametric so you can change inner cylinder dia and all boxes will adapt ;)
