AlexLoop Gear Reduction

thingiverse

The AlexLoop Mag Loop antenna (http://www.alexloop.com/) is a phenomenal portable HF QRP antenna. It has very high Q resulting in narrow bandwidth. The tuning knob is extremely sensitive. This is a planetary gearbox reduction gear to allow finer tuning options. I started with the NEMA 17 gearbox by user jag (https://www.thingiverse.com/thing:8460) and butchered the poor OpenSCAD file to make what I wanted. (Remix lookup on create thing is broken.) On the Carrier.stl, I drove a long M3 screw down the shaft to keep the shaft from shearing off. I liberally filled the gearbox with SuperLube (PTFE Synthetic Lube).
