This is a "Beefy" version of the propeller mount found on the UMX Sbach and UMX Beast 180 Brushless Motors. (3 pcs so you always have a spare and also to help absorb the startup costs shapeways charges)
This mount has been redesigned to use GWS props & have a larger backing surface for the propeller to rest against. And no additional spacer is needed to give the propeller space away from the cowl. This will help prevent the mount from breaking right behind the propeller. I also redesigned the area that bolts to the motor to give a little "give" in the event of a crash or hard propeller strike.
All that is needed to complete are the screws used with the stock 180 propeller mount and a GWS Propeller. I recommend using a GWS 5030 for the UMX Sbach and a GWS 5043 for the UMX Beast.
