Eustathios-mini

I am creating a smaller printer and I wanted custom parts to be designed with OpenSCAD, so I built it. It utilizes 20x20 extrusions and is targeted at achieving a build volume of 150x150x150mm. My first steps are detailed in the following video: https://www.youtube.com/watch?v=cCILGFZpqbU. I have successfully integrated a belt-based z-axis solution, powered by a PG-35 geared motor (or an equivalent Nema17 if preferred). This system has enabled successful prints, as showcased in the accompanying video: https://www.youtube.com/watch?v=vHuD2j9A_to&feature=youtu.be. Please note that I have implemented an updated version of the hotend holder, which now employs an IGUS RJMP-01-08 plastic bearing due to issues with my original PLA-based bearings wearing down too quickly. Assembly instructions are listed below: Required components: 20x20 extrusions: 8 x 240mm and 4 x 320mm. Bronze bearings: 8 x 12mm OD, 8mm in size. Chromed hardened rods (straight): 4 x 250mm in length. Smooth rods for crossbar: 2 x 220mm long. Ball bearings: 2 x LM8UU in quantity. GT2 pulleys: - Teeth count of 20, with an 8mm bore diameter, in quantity of 10 - Teeth count of 36, with an 8mm bore diameter, in two instances Closed GT2 belts, totaling 202 teeth in number: 2. Additional materials needed: 5mm bore 20-teeth GT2 pulleys: 2 x items required Two meters of open-ended GT2 belt available for purchase Fasteners include M6 dome-head hex bolts in lengths up to 16mm, square nuts for T-slots with a diameter of 8mm (used sparingly), M5 square nuts, and other hardware components (including M3 fasteners used in nema17 stepper placement). Pieces of toothpick will be necessary for wrapping around the belt during installation, followed by folding the belt inside its designated slot on the XY carriage parts.
