IKEA Billy door pull drill guide

The IKEA Billy bookcase 203.238.05 comes with a wooden "knob" to open the doors. I found this neither ergonomic nor aesthetically pleasing, so I wanted to replace it with a brushed satin drawer pull. The drawer pull I'm using is 3" (76mm) on center) for the screws. This drill guide should locate off of the pre-drilled hole for centering, and provide properly spaced holes for the new handle.

This piece is relatively thick to help keep the drill bit square with the door. The guide pin is tapered to make it easy to insert into the hole, and the alignment tabs have a draft on them to make it easier to get onto the door, and for some added strength.

The drill bushings are sleeved, with a taper towards the door. This should mean that the typical forces on them from the drill bill will tend to pull the piece together, rather than tear it apart.

Notes:

You should print this flat side down, but I don't know how to rotate the STL file.

I made some design decisions to optimize this for 3d printing. Try printing with at least 0.9mm wall thickness, to make sure that the drill bushings are as strong as possible.
