Greg wade accessible extruder/ AB_design

thingiverse

Tired of searching for an extruder suitable for my Prusa i2 and its hot-end, I designed a remix of the Greg Wade accessible extruder. The extruder was not available in the 1.75 mm version; it used 3 mm screws that are difficult to find with a suitable length in Brazil. Moreover, the hot-end did not have enough space for a fan, which caused filament traction problems due to the lack of an entry guide. I think I've also improved the overall design. In summary: -1.75 mm version -adaptation to using 4 mm diameter screws -there is no need to use a spacer/thermal barrier between the hot end and the extruder -more space available for the fan -added a guide that leads the filament to the traction gear, thus improving performance with flexible filaments.
