Commercially available bit holder attachments for the DeWalt belt clip screw/rails proved to be disappointing, holding a maximum of 3 larger/6 small bits per side with a still relatively high profile, and taking away the ability to stand the tool on its base while the battery is removed.

• Ability to hold 13 bits (4 long bits/adapters + 9 short bits)
• Easy to insert/remove bits with precise tolerances
• Locks in place securely with 2 belt clip screws
• Preserves ability to place tool in upright position on a surface even with battery removed
• No magnets required
• Lightweight

This attachment is more specific to DeWalt brand since it symetrically hugs the rubber rails on both sides, and uses both screws (I recommend a standard M3 x 10mm hex/allen screw instead of the philips provided).

Prints well in PETG/PLA/ABS, standing up, with supports (on build plate only), and an 8 mm outer brim (0.03 brim-object gap). For DeWalt yellow color match, I recommend Hatchbox Dark Yellow PETG/PLA https://amzn.to/4a1wHG6
