This is a mounting bracket/holder for your Milwaukee Impact Driver. This bracket was designed for the 2953-20 impact, but I have tested it with other impacts I have and it worked great also. I uploaded the print profile using PLA, but I would consider where you're mounting it so PETG, ASA, ABS or other temperature resistant filament might be a better option for you. The mounting holes are made for ¼-20 countersunk screws. If you have any suggestions for improvements or additions, please let me know!
