This model is a mount to hold onto your Milwaukee drills. It was designed for the Milwaukee 2906 model drill, but I have confirmed that it works with other Milwaukee drills and impact drivers. It's possible it could be used for many other brands. I printed it with PLA with a 20% Adaptive Cubic or Gyroid infill and at least 3 walls for strength. The mounting holes are for a ¼-20 countersunk screw or similar. It works really well to organize your drills. Please leave a comment or a picture of your print, I'd love to see where you chose to mount yours! Also, if you have any ideas for improvements or modifications for this model, feel free to let me know. Thank you!
