  • Universal stand-alone filament spool holder (Fully 3D-printable)

    This is quite ingenious, and all the parts print and fit quite well (I didn't end up using the wheels as intended... just put them in the slot and no axle). However, the problem I'm having is one of physics... your video shows the filament coming nicely off in an arc and entering the filament holder at a nearly straight angle. In reality, as the spool spins, it ends up approaching the entrance to the filament holder at a much sharper angle, creating a point where the filament won't make the turn through the holder. I'm starting with a full roll (8" diameter, 1kg), so it's already as far out from the centre as it will get, and this situation only gets worse the smaller the radius of the remaining filament gets. Did you run into this, and did you figure out a way around it? Any ...

Did you run into this, and did you figure out a way around it? Any chance you have a redesigned filament holder that is at a non-tangent angle to the spool? I wonder if using a small section of filament tubing on the intake side that arcs toward the filament roll would alleviate the issue?I printed all the parts on a Bukito3D (it was one of the first things I printed on my new printer!).
