Anet A8 Filament Release Handle

thingiverse

Every time I changed filament in my Anet A8 printer, I ended up with a bolt embedded in my finger. This frustrating experience prompted me to design this release handle. It's intended to slip over the tensioning bolt on top of the feeder. This is an updated version of my initial attempt; the original one worked but had to be twisted at an awkward angle. This revised design performs better. Print Settings: Printer: Anet A8 Rafts: Don't Matter Supports: No Resolution: 0.1 Infill: 20% Notes: The .STL is saved upside down for easy printing. Supports shouldn't be necessary, as the model should print freely. Post-Printing It might be essential to enlarge the first millimeters of the hole in the shaft slightly so it fits snugly around the nut.
