SJP Quick Change Spool to hold 5 lb filament by SaintJProductions Feb 2, 2013

Description

*WARNING: be sure your filament roll is wrapped from the inside out. otherwise tangles will result and filament will jam.
V1.1 Spring holds not strong enough to keep arm closed.
* PLANS: New arm releases, Hole to hold filament ie start of spool inside end (both 3mm and 1.75mm), tips of arms to tilt to inside to help with unraveling, more spokes in hub to keep filament circular.

This was created to hold 5 lb of filament.

Based on murat's 1 lb design

One of the arms allows collapse to ease reloading of a fresh spool
