Phantom 4 Motor Cap Test Ring

If the Motor Cap design https://www.thingiverse.com/thing:1437067 is not giving you a nice push fit on your machine, this is a 'test' hoop that you can scale up or down to suit your particular printer without going through a complete build each time!

The original size works fine on the Afinia Up!, but you may need to up/downscale by (hopefully no more than!) 1 or 2 %

Hopefully this will solve things...
