This is a slightly larger version of my EasyDrill holder (https://www.printables.com/model/214238-bosch-easydrill-cordless-screwdriver-pegboard-moun) - the UniversalImpact drills have a slightly larger body.
Print in PETG, with 3 perimeters and 20% infill. Use two Spax 4x12mm panhead screws (or other wood screws with panhead) in the back for mounting.
