RollerTrol Adapter for 38mm Diameter Roller Blind

I made these adapters to fit the RollerTrol TMDC-12-25-15-28-R Tubular Motor into my existing Blinds (see the picture of the "internals" attached).

Although the motor fits into the tube without these inserts, the tube will not be always centered completely. The inserts will center the motor for an especially smooth "ride" ;-)

The STL's for the individual inserts are added as well to allow the motor adapter part to be reused in your own
