Get omnifixo at https://omnifixo.com/

Simple base for my omnifixo M4.4, with some storage space for my Xiaomi Electric Screwdriver and its bits set. 

The omnifixo is held in place by round 5x2 mm magnets. There's also space in the base for larger 40x20x2mm magnets to hold the bits (you should stop the 3d printing at some point to place these magnets and resume the printing).
