5/64th Drill block spacer

This is a spacer for a US 5/64th twist drill to be used in a Hand-Held Drill Guide. Tested and used with a Miles Craft brand Drill block Model # 1312.
I need to drill pilot holes of 5/64th and the drill guide i have doesn't have a marking. This spacer fits great when printed in PLA, 25% infill.
It prints upside-down. The top is intended to stop it from falling through when picking up the drill guide,
