Extruder and X-Carriage update

I added a fan grill over the hotend fan and I also added a thumb lever for the extruder to make it easier to press down on and manually release the filament.

In other news I also added screws and nuts to the model! I have some revisions to go through still but at this point it is purely just polishing work.

I'll make a second post today to keep up with my daily posting. I really aught to work on some assembly drawings for a kit version of this printer.

Cheers!
