Pico Extruder with 603zz bearing

thingiverse

This is a Pico extruder remix equipped with a 603zz bearing and a TPFE outlet tube guide. Additionally, a hex nut has been installed to securely hold the bearing in place. Noting that the original Pico design utilizes a hex hole, I opted for a circular mounting point instead. Since an MR85zz bearing was unavailable, I substituted it with a similar bearing model that works well with PETG filament and meets my testing requirements.
