Eustathios-mini

I am designing a smaller printer, and I'm creating its components with OpenSCAD to make it happen. The design utilizes 20x20 extrusions and aims for a build volume of 150x150x150mm. Check out my first steps at https://www.youtube.com/watch?v=cCILGFZpqbU. I've added a belt-based z-axis solution that uses a PG-35 geared motor, or you can opt for a regular nema17 if preferred. My printer is finally printing: https://www.youtube.com/watch?v=vHuD2j9A_to&feature=youtu.be. Please note I've updated the hotend holder to use IGUS RJMP-01-08 plastic bearings instead of my worn-out PLA ones. To build this, you'll need: 8x 240mm 20x20 extrusions 4x 320mm 20x20 extrusions 8x 12mm OD, 8mm bronze bearings 4x 250mm chromed hardened rods (make sure they're straight) 2x 220mm smooth rods for the crossbar 2x LM8UU ball bearings 8x 8mm bore 20-teeth GT2 pulleys 2x 8mm bore 36-teeth GT2 pulleys 2x 202 teeth closed GT2 belts 2x 5mm bore 20-teeth GT2 pulleys 2 meters of GT2 open-ended GT2 belt 8x 16mm M6 dome-head hex bolts 20x M5 square nuts for the t-slot 20x 8mm-long M5 dome-head hex bolts (I'll add more as the build progresses) 8x 8mm M3 bolts for nema17 steppers To assemble the belt, use pieces of toothpick to wrap it around and insert the folded belt into the slot of the XY carriage parts.
