Antenna Knob

I was tired of fiddling with the nuts of the fpv-antennas on my skyzone 04X, as the two antenna-sockets are somewhat close and/or my fingers are somewhat big.
So I designed a ring made of TPU that snuggly fits onto the hex but is made from TPU so it doesn't bend the nut or otherwise influence the connection.
Size of the hex on the nut is 8mm, I usually need 0,075mm of oversize for my printer, but it turns out the hex clamps with those 0,075mm just nice.
In order to not have those dreaded strings - which is already reduced by the slow print-speed - I print the knobs one at a time.
