Tiny drill bit collet for regular drills
Description
I got a set of drill bits smaller than 1/32" that are so small they don't fit in my regular electric drill. I made this adapter, known as a collet, to squeeze hold of the drill bits for use with my regular drill. I used a 3/64th bit to widen some pads in a thru-hole PCB. The STL file will work with 1/64, 3/64, and 1/32" bits as is. If you need to go smaller than 1/64", adjust the scad and export your STL. The scad is parameterized so you can easily adjust the center hole, the slot gap, overall height, and the base pad.
