by SaintJProductions, published
*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
V1.1 - removed cross brace support to use less plastic and ease access to spring/band hooks.
