Spool Arm for PRUSA Original/Enclosure Spool Holder Base

Please use stronger materials only, preferably PC, as this arm holds spools that are heavy. Prints made of PETG or weaker material MAY BREAK.

If you want to change the size of the arm, add 21 mm to your desirable size in your slicers Z Scale factor. For example, if you want size to be 100 mm, change the Z Scale factor to 121mm.

There are two versions of the spool arm for two different Original Prusa Spool Mounts.

1. PRUSA_spool_holder_arm_75mm.stl
2. PRUSA_spool_holder_arm_original_75mm.stl

PRUSA_spool_holder_arm

This version is made to fit Prusa enclosure spool holder base (left or right).

Printed in size 75 mm is perfect for the inside of Original Prusa Enclosure as the printer extruder head or the printer bed cannot hit the spool.
