Watch Kit Bit Holder

The comprehensive Watch Repair kit that I purchased came with a bunch of bits that were in plastic bags so I quickly created this on Tinkercad so that I could get rid of the little baggies. The holes are 3mm diameter with 3.7mm across the middle to account for the part of the bit that holds them in the handle. I enlarged it by 3% in printing to accomodate for the shrinkage of the filament which made the fit too tight.
