Prusa I4 Fast Filament Change Lever

thingiverse

February 2018 After six months of use, the front leg slid off, so I decided to beef up its design a little. Probably won't happen if you print at full capacity anyway, but no reason not to fix it. April 18, 2017 I just updated my model. The one I was using snapped after a few months, and I saw it was incredibly thin on one end, so I reinforced it a bit. It still fits perfectly as before. ;) Have you ever wanted to switch filaments in the middle of a print or change filament color without having that option? This modification will help you out. You'll have to remove the step motor and its arm in order to install this upgrade. I just uploaded a lever with a hole for the Allen key. It doesn't look like it should compromise the structure's integrity. Enjoy! Print Settings Printer: Prusa I4 Rafts: No Supports: No Resolution: Any setting is fine. Infill: The more, the merrier. Notes: I printed solid just to be on the safe side. Just make sure to turn it onto the correct side to avoid overhangs.
