3DM1 - RepRap 3D Printer

Find all (updated STL and OpenSCAD files) at https://github.com/makevoid/RepRap_3DM1, as this is a fork, simplification, testing of a modified who's Wallace design, in my opinion an awesome simple design, upgraded to suit our needs. The STL of parts all on the print plate is just for display; you can use them, but likely find updated files (and customizable OpenSCAD files) in the GitHub repository. There's a download zip button on GitHub on the right! All STL files are found within the folder unsurprisingly named "stl". No images: missing pictures of other 3DM1 printers hopefully added soon. The printer design is a collaboration between Giuseppe Di Marzo and me. The last photo is of a recent print, made at 0.25 layer height - 0.35 nozzle size, with very low outer shell speed (65 inner shell speed). The model used was the T-rex by Makerbot Academy: http://www.thingiverse.com/thing:308335. **Build Your 3DM1** Print area measures: build plate is made of Acrylic at 0.8mm, while printer size is scalable to your choice. Start by scaling the X axis, then the Y axis, and finally the Z axis; this allows easy scalability. Unlike some designs, no fixed measurements are required, thanks to the smooth rod, threaded rods, and two pieces of acrylic build plate which can be resized to fit your needs. A 32cm x 22cm x 18cm (XYZ) print area is possible with our chosen setup, using 8mm rods for all components. Should you prefer, use 12mm rods on the X and Y axes for greater stability, or just 12mm rods for structural elements while employing 8mm smooth rods for movement. The Z axis also offers options, such as employing smaller threaded rods (6mm) for increased precision in small print settings. Remember to adjust extruder nozzle size accordingly based on the final printer dimensions - e.g., use an appropriate size suitable for a 12x8x6-inch model. * When choosing axis values: Make X the longer axis. Make Y shorter than X. And if applicable, Z slightly shorter than Y (except where securing it to a surface). - This approach results in an easily built printer, perfect for personalization and modularity!
