This is a clip on external spool holder for printers that are stored close to walls.

It uses the pre-existing mount and ptfe tube screw.

V2.1:

Has increased support to prevent supports detatching early.

V2:

Has increased wall thickness and altered print direction to improve strength.

Recommendations:

• Make sure your build plate has been cleaned before printing, due to the thin supports it has potential to lift.
• To reduce sag and strain on the arm i recommend using thin double sided tape on the bag of the arm 
• I would recomend printing in petg however pla will work too
