Ender3 Filament Guide ==================== There are many cool looking and thoughtful designs one can print to fix the notorious Ender filament chafe issue like these: https://www.thingiverse.com/thing:3315565 https://www.thingiverse.com/thing:3038801 https://www.thingiverse.com/thing:3342775 https://www.thingiverse.com/thing:3576034 https://www.thingiverse.com/thing:2853267 https://www.thingiverse.com/thing:3061551 https://www.thingiverse.com/thing:3184816 https://www.thingiverse.com/thing:3065048 https://www.thingiverse.com/thing:4024617 And here is one with a runout sensor, very nice! https://www.thingiverse.com/thing:3357097 Why I designed this: --------------------- - Fusion 360 practice - Make something unique and beautiful. - Improve a product. - Stop a print and insert a foreign object. - Get better with snap fits. - Improve my design for additive manufacture thought process. - Give back to the open source community. Design requirement needs: --------------------- - Have a large curved surface for the filament to run. - Smooth running with minimal friction. - Inexpensive - Print without support - Use readily available parts - Aesthetically pleasing Ingredients: --------------------- ####PLA - 7g - 2.34m - 1hr6mins for the bracket
 - 19g - 6.47m - 2hr53min for the shiv ####Balls - 4.8mm balls ideally (realistically between 4.7 to 4.9mm is probably ok)
I used worn out steel balls from a bicycle hub. Anything spherical of the correct size will work. Happy making! :) printornaut <- that’s me on insta I gleaned inspiration for using steel balls in a cage by watching this video: youtube.com/watch?v=RPXKK6NsMaM&t=1s
