I designed this to be mounted on the lid of a tool box, to fold out when in use and parallel with the lid when not in use. The flat back makes it easy to glue onto a lid or wall, it also has a flat bottom and can be attached to a horizontal surface as well. It only holds 4 bits as it is intended to be semi-modular, easy to print multiple and line them up vertically or horizontally.
The holes for the bits are just over 10mm deep which leaves plenty of space to grab bits. The bit holder can hinge between two angles, vertical and 30 degrees. The bits are held 5mm out from the wall when in the vertical position so theoretically you could fit a 16mm hex bit. The bits are not held in tightly and have room to move, making it easier to get them in or out, the magnets hold them fine.
The bit holder simply snaps into the hinge from the top by pushing it straight down.
I printed it out of PLA with a 0.2mm layer height and 20% infill but any filament should work.
The actual bit holder prints best upside down, that way no support is needed.
You will need 4 2x8mm magnets. You will need to modify the gcode either manually or with your slicer to have it pause at the right time to insert the magnets, they are quite a tight fit. I got them started by hand and then finished inserting them with the end of an L key.
Note: It is very likely you will need to scale the model slightly in your slicer depending on the accuracy of your printer to get the magnets to fit snugly but not loose. The same applies for the fit of the hinge.
Please comment with any suggestions or questions about the model and I'd love to see some remixes!
