Prowin CNC Hopup Arm - Original and Flat

thingiverse

A perfect replica of the hop-up arm found in the Prowin CNC hop up chamber is provided. Two versions are included: a direct copy of the original part, as well as a modified version with a closed-off end suitable for R-hop and similar applications. The original component features an angled tooth that inserts into the hopup wheel. This design element makes the model particularly challenging to print on FDM printers using ABS material due to warping that occurs on the slanted side. Therefore, it's recommended to use the FDM version with a flat bottom side instead, and then sand or file the bottom surface of the tooth to match its upper surface. For SLA printer users, both sides of the tooth can be printed slanted using the SLA version.
