Clips to hold 1/4" (6.35mm) XLR (or USB or power) cable to an inexpensive scissor-arm style microphone stand made of 10mm square tubing. The one in the pictures is a $14 "Adjustable Microphone Suspension Boom Scissor Arm Stand" from that one site that sells everything.
Modeled with exactly 10mm square gap inside clip, so it scales easily to whatever size you may require. It actually worked a little better printed at 103% scale with the PLA I used, to account for shrinkage. Pictures are of 100% scale, and you can see that they bow out a bit on the 10mm square tube. 103% scale prints don't bow from my printer/PLA combo.
Prints four clips at a time. Even with a raft, 3 walls, and 25% infill, it only took 45 mins to print on my old Makerbot Mini+.
