Universal Prop Mount v2 20mm Compact STL
The Universal Prop Mount v2 Compact is a generic design made to fit anywhere on a coro prop where there is free space and is made specifically for 20mm conduit. This version is a more compact design compared to the standard v2 design which can fit into tighter places. The rectangular base measures 76.2mm x 44.45mm.
