The Creality Ender 3 Neo is a great budget printer, but it does need quite a bit of tinkering to get the best out of it, and here’s a really easy - and cheap - way to significantly improved its performance.
My specially designed, 3D printed filament guide takes the pressure off the standard plastic extruder by ensuring the filament is fed in at a shallower angle, reducing friction, and the likelihood of miss-printed layers causing the whole print to fail.
Mk2 is even better, with a Lego pulley wheel to further reduce friction for confident printing of even the longest jobs.
If you are inspired to make your own, the .stl file for the design can be downloaded from paterpracticus.com/downloads
The Lego spoked pulley wheel (part no 30155) and axle (connector peg 39888) can be easily sourced from ebay or other suppliers.
