Alternative spoolholder

cults3d

My Vertex K8400 printer's built-on spoolholder is fitted with excellent roller-bearings - and that's a good thing... most of the time. (And the same will go for many other printers out there). In this particular case, I have quite good filament that's wound on a spool with an unbalance in it: so every time the heaviest point goes over the top-center, the spool goes on for a bonus half a round & uncoils its filament in the process. As you can imagine, after a few spins, things are getting nasty. This alternative version of a spoolholder doesn't use bearings - it uses a simple fixed axle, providing sufficient friction to prevent the unwanted uncoiling. My expectation is, that I won't be needing this spoolholder that often, but I will want to use it every now & 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)
