It looks like you've shared a comprehensive guide on building a 3D printer! Here's a summary of the key points: **Parts List** * 3mm guide (fixed to body) * Filament driver (11mm diameter) * Hot-end (cheap Chinese one, dimensions in pictures) * Stepper motor (Nema 17 x 47mm, strong motor recommended for 2.85 & 3mm filament wire) * Driver (A9844 with heavy cooling and heat sink) * Main body (with support material) * Z axis setup: + 16x 608ZZ bearing + End switch + M8 bolt or threaded rod 85mm and nuts + Spindle 8mm and spindle nut or M8 threaded rod and nut + Stepper Nema 17 (2x) + Motor to spindle connector 5mm to 8mm + M4 bolts, nuts, and washers * X and Y axis setup: + Sliding rods (10mm length, choice of user) + Linear bearing LM10UU (4x) + Linear bearing LM10UU in housing (4x) + F623ZZ bearing for timing belt tension-ers (6x) + Timing belts and pulley's (3x) + Stepper Nema 17 (3x) + End switch (2x) + LED strip (optional) + Fan (30x30mm, optional) + M5 bolts, nuts, and washers * Extruder: + Bearing 608z (3x) + 11mm driver + M8 x 50mm bolt or similar + Hot-end + Snail house fan (2x) + Spring (optional, depending on filament material) + Nema 17 stepper + Kapton tape **Marlin Script** The script is included for printing with PET-G 1.75mm and has the following settings: * Flow-rate: 49% * Steps/mm for extruder motor may need tweaking **Notes** * The guide is a good starting point, but users can modify it to suit their needs. * The printer uses an open structure, which may cause warping with ABS 3mm filament. * The author recommends using a strong stepper motor for 2.85 & 3mm filament wire. Overall, this guide provides a comprehensive overview of building a 3D printer, including the necessary parts and settings. However, users should note that this is just one possible implementation, and they may need to modify it to suit their specific needs.
