thingiverse

UPDATE: as form user suggestion additions: * Increased lever length for easier use. * Added space washers to improve bearing movement. * Slightly moved the PTFE tube 0.5mm for easier use. * Moved the spring hole 1mm. This is a modification of one of my old works, changed the lever to fit a standard Creality feeder. Improvements: * PTFE tube on the filament entry in order not to make the filament touch the threaded rod, you can just curve it a bit and it's ready. * More solid lever, with two plastic parts, and a longer nut. * Adjustable spring for pressure control, the original one isn't great in many cases, using the little plastic nut and the lever without the bolt will be the same as the original one distance. Things needed: * M4x10mm bolt for the bearing (original one is shorter) * M4x20mm+nut for spring pressure control * For the other parts you can use the original nuts Mounting: 1. Force press the lever and cup together, insert the bearing and screw the nut in the plastic, check if the bearing spins without problems. 2. Cut a piece of PTFE tube, I suggest not less than 30mm, force press it into the hole, and you are done. 3. Force press an M4 nut into the spring controller, and then screw the M4 bolt 4. Mount every part, then put the spring with the cap in the feeder. Printing: Suggested material: PETG or ABS Infill: 40% at least
