Creality Ender 3 Bowden Holder (my overreaction to slippage)

thingiverse

I've got it printed out, but I'm not sure how well my makeshift fix will hold up to keep the Bowden tube retained in the extruder. This might be a temporary solution while waiting on a shipment of proper couplers, or it could be completely worthless. Who knows? It looks like it should work though. To do this repair, you'll need three zip ties - the ones that fit through the slots. Two go around the barrel of the device and get tightened until the Bowden tube doesn't slip out of the jaws. The third goes around the extruder stepper and through the holes in the backplate to hold it in place. There's a built-in rounded spacer at the bottom of the backplate that helps with tension, more zip tie tension equals more "pull" toward the extruder. With some luck, there should be enough flex in the pieces that you can tightly slip the Bowden tube through the slot in the top of the barrel without having to undo anything, and you could potentially add this fix mid-print if needed.
