Hobbyzone Champ S+ propeller-adapter wrench

The Hobbyzone Champ S+ is a great little plane, but the propeller-adapter is a well-known weak point.
Removing and installing the adapter can be difficult because it is hard to get a grip on the motor (recessed in the cowl).

This wrench is designed to slip in behind the propeller spinner and hold the motor.

This may also work with other planes that use the same adapter (EFLU4067), but the clearance can be tight and I don't have any other models to check it on.

The STL-file to print this is at:

[Update: thingiverse's website is having some problems, so I'm posting all the photos, the STL file, and the OpenSCAD design here too.]
