Adjustable spool holder for top bar of printer. You will need a spare piece of EMT from your Piper build unless you want to purchase another 1 (Its cheap enough!!)
Solid Navy Blue
Printed with 3 walls (1.5mm shell).
You will need 4 m4x14 screws and m4 nuts... 1 for each Spool Stopper, and 2 for the EMT clamp.
I printed these in PETG for added strength when tightening everything with the screws.. PLA could work, just be careful not to crack the pieces when tightening them.
