Alternative spoolholder

thingiverse

My Vertex K8400 printer's built-in spoolholder is equipped with top-quality roller-bearings - and that's a good thing... most of the time. In this particular case, I have excellent filament wound on a spool with an imbalance in it: so every time the heaviest point goes over the top-center, the spool makes extra turns & uncoils its filament in the process. As you can imagine, after a few spins, things get out of control. This alternative version of a spoolholder doesn't use bearings - it uses a simple fixed axle, providing enough friction to prevent unwanted uncoiling. My expectation is that I won't need this spoolholder often, but I will want to use it every now and then: so, this is what I came up with... When not needed, it can be tucked away in a drawer without taking up much space. You'll need: - 2 off - Frames "Spoolholder Alt" - provided as STL and STEP versions. - 2 off - M8 threaded rod (or equivalent) - 8 off - M8 Nuts - 8 off - M8 washers - 1 off - Center axle (I used a piece of rolled-up cardboard for now). Optional: 4 off - M8 covers, to avoid damage from the threaded rod ends. (As the Vertex was busy on another print, I printed this set on the Opiliones 2L)
