A small frame for a loop antenna made from RG8 coax. Based on this video's dimensions https://www.youtube.com/watch?v=Ivr9VbSgjUU , just with BNC connectors. The frame is to support it since RG8 is quite thin and flimsy. The loop is approximately 250 by 275mm and the frame accomodates a BNC tee on the bottom to slide over and stay secure. There are also zip tie holes for the coax. To assemble, just superglue the cutout areas together.
Ziptie the antenna in and insert the BNC tee into the cup at the bottom. You can swap BNC tees from male to female by removing the BNC's and pulling the tee out, leaving the antenna tied to the frame.
The parts will both fit side by side on a Prusa MK4 bed at 45 degrees. Look out for warping though, you can see where mine did.
