Cover and adaption parts for the POTY ("Patch of the Year") QO-100 feed

These are cover and adaption parts (40mm to 22mm ring for the LNB mount and a POTY to LNB waveguide adaption) for the POTY QO-100 feed (thanks to Mike Willis G0MJW, Remco den Besten PA3FYM and Paul Marsh M0EYT for this great design and their great work).

The parts are for a (kit) design available e.g. at Hans Holsink PE1CKK, Passion-Radio or IBJ.

I printed the parts with black PLA and white ABS with 0,2mm layer height/25% infill/0,4mm nozzle and they fit well. The final version is made of ABS, because it is UV- and shock-resistant and has good RF characteristics. Be aware to retune the patch with cover (it has an obvious influence!). The adaptor ring can be cut on one side. I used a bit of adhesive tape to support the other side, because if bended more than two times the material may break and you'll get two parts.

The parts are modeled with FreeCAD.
