5mm nut driver handle (using nut driver from new PC build fixings)

thingiverse

This handle is designed for use with one of those small screwdriver nut adapters you find in some PC case fixing kits. It converts the adapter into a nut driver that can be used in various projects. Simply attach it to the end and secure it in place with glue, though you may need to warm the nut slightly before pressing it in (not scorching hot). The handle has a 1.2mm shell with a 25% infill. For printing, use a brim or raft if necessary, as it will be relatively compact.
