There are Milwaukee Tool style holders for OMT blades. They should work in the wide Milwaukee accessory cases and my Packout bit trays.
These have been tested with Dewalt, Bosch, Milwaukee, Rockwell, Ridgid, and Fein blades, but any blade that has the notches in the right places should work.
I’ve created two different STL files. The single for wider blades, and the double for two narrower blades side by side.
Printer: Prusa i3 MK3
Material: Inland PET-G
Resolution: 0.3 mm with a 0.4mm nozzle
Wall Lines/Perimeters: 3
Infill: Minimum 20% Gyroid. The higher infill percentage the stronger the part.
Notes: Do not change the orientation. Use supports touching buildplate.
Print the STL files with support touching the build plate as they are oriented in the files (lying down). I had several people who test printed these tell me that they snapped if they are printed upright.
Above I used PrusaSlicer and it generated the oversized supports. I tried slicing it in Cura and it generated much more modest supports which cut the print time by 10-20%. The oversized PrusaSlicer supports might be easier to remove though.
