Prusa Mk3 1:4 scale xmas ornament

thingiverse

As part of an upcoming competition to design a Christmas ornament, I made a 1:4 scale version of my MK3 printer. This is quite accurate dimensionally, although not perfect and with some liberties taken to make it printable. The model was designed in Fusion 360 (no parts are re-scaled from the original Prusa models, since most would be unprintable). No supports are needed for any parts. The assembly should be relatively self-evident. All the rods are silver 1.75mm filament. All the cables are black 1.75mm filament. You will need a lot of superglue and reasonably steady hands to assemble and glue (I suggest using a lighted magnifier to do this). All part dimensions have been optimized for a 0.4mm nozzle (0.45mm line width) at 0.2mm layer height. You could likely print okay with a smaller nozzle, but I wouldn't recommend anything larger. I used: * Fusion Filaments Carbon Rod Black HTPLA+ for the frame. * Solutech Navy Blue for the printed parts of the original printer (to match my printer) (I may print another copy using Fusion Filaments Radioactive Orange to look more like a stock MK3). * Fusion Filaments Cold Fusion Blue for the LCD screen. * Filamentum Rapunzel Silver filament for the rods. Update: 12/21 - I have uploaded the parts for the R2 Extruder assembly and posted photos of the completed assembly. Update: 12/8 - I added the heatbed and connector, and fixed the Y carriage (which was offset to one side due to an incorrect measurement). I hope to get time to do the extruder in the next few days and also plan to do a separate print surface so it can be printed in a gold-ish color. Note: The image of the model with orange parts is a render that I did in Fusion360, which came out pretty nicely I think. (But I couldn't find any Christmas-y HDRI environments)
