This model is for those micro bits for small screwdrivers, not the larger quarter inch hex size.
The original model is here:
https://makerworld.com/en/models/438635-hex-bit-holder-for-95-bits
Scale it to 64.50% of it's original size.
Printed at 65%, it was a tad loose, and at 64% they were somewhat hard to get back out.
