Filament Guide Stacker

thingiverse

This system accomplishes several objectives. It ensures that filament pulls off spools at a consistent, low-resistance angle by following an arc at a fixed position and angle. Without this setup, filament would pull off spools at extreme angles, causing spools to bounce around during reversal and Z movement. Additionally, it eliminates the need for spool housings since filament remains securely in place due to the fixed angle of extraction. The system also prevents unraveling when Z homes, as the tube rises instead of the spool becoming disorganized. Furthermore, it simplifies switching between spools, as the tube retains filament in place when removing a spool from the extruder. Lastly, it provides extra storage for tools. To set up this system, print out the specified part and attach it to your 3D printer using screws or simply snap it together if you have two stacked spools. Note that using a tube to guide filament is crucial; a 6mm OD tube is recommended, which can be press-fit into the holes on the side of the system. Approximately three feet of tubing should be sufficient to create a gentle curve, reducing resistance. Alternatively, you could mount the system on the back left of your printer, potentially allowing for a more aesthetically pleasing curve through the tubing.
