Intended for use with futaba S3003 servo motor with simple aluminium support.
Fits perfectly with skywatcher 50ED
You will need a bunch of M2.5 screws+nuts, but M3 will fit with a bit of rework with a drill (can be done after print)

I printed with green PLA at 195 degree (bed at 50 deg), used 1.6 mm wall thickness with 30% fill. It is solid enough.
