Easy open/close belt Extruder for 1.75
thingiverse
I wanted a simple way to swap out the belt on my 1.75mm extruder. I drew inspiration from two things: the Hobbed Bolt system found at https://www.thingiverse.com/thing:1764551, paired with a 60-GT2 aluminum pulley, and the easy-access design showcased at https://www.thingiverse.com/thing:1579394. Changing filament is now a breeze - it's quick and fun! I've had this setup up and running for three weeks now, and it's been working great. I'll be posting some photos soon to share with you all. Have a great day! Here are the parts I used: * One 60-GT pulley * One 16-GT or 20-GT pulley * Hobbed Bolt with an 8mm shaft * One belt with a length between 200-GT2 and something else * One M5 push-fitting for 1.75mm filament * Two steel springs * Three 608 bearings - the type doesn't matter, but they should be 8x22x7 * Two M4 50mm (or longer) partially threaded socket head cap screws * Various m3 nuts, screws, and spacers * A Nema 17 motor
