I was searching for a Gridfinity holder for my iFixit Mako set, but wanted to keep the original case as I like this very much. This design is also very much inspired by iFixit Mako Screwdriver Set Gridfinity Holder by Tactical Grizzly, but I wanted to create a solution which enabled me to quickly grab the bit set without having the lid following along. The lid is still easily accessible for when needed.

The design has a standard Gridfinity magnet (6x3mm) embedded into the design which gives the satisfying magnet effect and together with the lid helps keeping the thing together. I just paused the print at the correct layer height and pushed the magnet into the piece and then continued printing afterwards.

Print instructions

1. Download the STL
2. Mirror a copy of the piece
3. Duplicate your two pieces to create a total of four corners
4. Add print pauses before the top layer of the magnet shelf to insert magnets
