OMT Blade Holders for Milwaukee Packout Bins

OMT Blade Holders for Milwaukee Packout Bins


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
Slicer: PrusaSlicer
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.

OMT Blade Holders Printed Supports

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.


  1. Great print, had to do some resizing. I originally printed standing up and sure enough the pegs snapped right off. However I brought it in to Sketchup and moved the peg body lower into the mount body rather than just sitting on the surface of the mount. This effectively integrated the peg into the body of the mount. All is good now and nothing snaps off and I can print vertically without supports. To fit Milwaukee brand name OMT blades satisfactorily I had to size the pegs and peg “fins” to 90% of the size of the original.

    1. First off that’s strange about the Milwaukee brand OMT blades…several people tested them for me and they worked fine. Maybe I’ll look into that if I have time.

      So you moved the peg body to the edge so that it was bonded with the outer perimeters? Makes sense. Several people that printed the holders in PET-G with the Prusa printers said they were fine to print standing up. I tried one on my Prusa and I couldn’t break it. But I know that many people don’t have their 3D printer dialed in as well so I designed it to be printed on it’s side.
