I bought a new Pin Vice recently and while the tool and bits are great, the box that the bits came in is not (I didn't fancy playing 20-bit-pickup every time I needed to change the bit) so I designed a new holder in Fusion 360.
It was designed with resin printing in mind, so the tolerances are very tight, but there is no reason why it can't be printed with FDM at a high enough resolution.
There are two versions included:
v1: This was the first version, with 1.7mm diameter holes (beware, if this is printed you may have to drill the holes out slightly for the larger bits, as they are a bit tight), and the lid just sits on the lip rather than securely fastening.
v2: This version features larger holes (about 1.9mm) and a ridge on the edge of the base so the lid will fit securely. It also features a recess to store the pin vice itself (and the lid has a hole that it can fit through). If you don't want to use the recess to store the vice, the v1 lid will also fit securely over the ridge, giving you a closed box.
