update v2: added solid top option to prevent smaller bit from falling out and increased the stopper size so the bit doesn't flop upside down and fallout.
this is a simple compact drill bit holder for large bits. to use print both parts screw the top on with inbuilt threads.
there are two ways you can use the holder.
to lock turn fully or until the hole is not alighted with any bits.
there is a small key in the top on solid and mesh tops for a Philips screwdriver if you are having a hard time screwing or unscrewing the top but be careful as it is still only plastic and will brake if too much torque is applied.
use supports on build plate only if you are having trouble printing the curve on the top.
more sizes coming soon.
