This is a customizable beer tap handle wall display (holder). It is scalable from 2 handles up to an infinite number as large as the wall is. This uses standard 3/8"-16 bolts, 1 inch in length with a low profile nut. The wall mount holes are for a #10 screw.

Each section supports 2 tap handles (side sections only support 1 tap handle), there is a middle section along with a left and right to close out the sides. For each section you will need 2 washer cover pieces, along with 1 covers for the wall screws. Purchased hardware would require 2X 3/8"-16 bolts and 2X 3/8" low profile nuts. Each connection will requires 2 pins.
All parts print in the orientation in the model. Center section and right hand side will need build support at the ends that have the bridge piece.
I used PETG but ABS would be fine. Might be able to get away with PLA at a higher infill percentage.
