Got sick of my standalone spool holder getting dragged around. This one clips to the top deck. I tried to get minimal overhang in both the x and z directions. The aesthetic is "harp wishing it was rims." Prints as 3 separate pieces; I couldn't finagle both clips to fit on the bed. Haven't put it to the test yet, so could get some small modifications in the near future. The two clips are asymmetrical and flat on one side. Surprisingly sturdy with low infill.
