This is a handful of printable replacement flanges for draft beer faucets.
The various models are:
A1 - Modeled after the standard black plastic flange included with most faucets.
B1 - Modeled after the larger stainless steel flange available from some retailers like MoreBeer.
B2 - Same contour as the above, but mostly solid to make it more durable & easily printable.
C1 - An alternate hexagonal flange design.
C2 - Another alternate hexagonal flange design.
The hexagonal flange was designed & printed for use with a 2" diameter black iron pipe draft tower, where I used a hexagonal bushing to mount the faucet to the 2" elbow. As seen here: https://www.youtube.com/watch?v=oAHQSl_99gs
Recommend printing at 100% infill as the pressure from tightening the shank will cause deformation.
