New version v3 on the link! There is new version of this design v3 Compatibility notes This version v2 Full resolution images are here OpenSCAD open source files are here. It is published as it is. Please don't make request for changes to me. Everybody can modify it yourself. This is the remix from original Scott's hypercube evolution. To build printer from the scratch you will need Z asis and hotbed STL parts from original. Don't forget to print inner part for tension from original HEVO Here you can found better cyclone fanduct update Major features of this thing 2x MGN12H on Y axis MGN15H on X axis direct extruder based on Titan AERO BLtouch 5015 blower holder to fix cables on head option to add optical endstops (I am planning to use TMC2130 switchless end stop) All remaining parts of printer could be same as Scott's hypercube evolution. Or you can use this my other modifications: * Hypercube evolution Z motor lower by 10mm * Hypercube Evolution (HEVO) bed leveling nut knob * Hypercube Evolution tennis ball damper Possible improvements: option for volcano hotend option for another exteruders (maybe E3D Hemera or Mellow NF-BMG Aero V6 better adjusting of BLtouch position Assembly instructions: mount MGN12 Y rails with carriage, but not tighten screws fully mount XY joins without idlers and MGN15 rail to MGN12H carriage. Do not tighten screws fully move X rail front and back and tighten screws on Y rail and XY joinder fully. It must move smoothly. insert idlers into XY joiners (useful helper is small piece of GT2 belt around idler to insert it inside easilly) mount fully assemled idler holders and motor holders. Assembly head tensioner and "back" part onto MGN15H carriage without 5015 blower stretch the belts and set proper tension finish head (front part, extruder, blower, cable holder etc.) BL touch position in Marlin #define NOZZLE_TO_PROBE_OFFSET { 19, 49.5, -2 } BOM (bill of matherial) 4pcs 3-way corner for 3030 profile.. It is needed, because my motor holders and idler holders are not compatible with inner "L" corners. MGN15 rail with MGN15H block for X axis. Length is your X 3030 profile length + 56mm (for standard 300x300x300 it is 476mm) 2pcs MGN12 rail with MGN12H block for Y axis. Lenght is same as your Y 3030 profile ((for standard 300x300x300 it is 410mm) I recommend this high quality GT2 pulles. 2pcs without teeth 6pcs with teeth. Far better than china standart, but with 10mm width, this design accept this one or standart chep one. 2pcs GT2 Belt Pulley 20 teeth M3 hammer nuts for 3030 profile to mount MGN12 Y rails lot of DIN912 M3 stainless screws. I can recommend this set, but need more screws. For ex cca 16pcs M3x12 to mount Y rails. M3x5x5 brass insers to plug into plastics. Don't ask me for the nut version of printed parts. Brass inserts are far better than nuts, specially in PETG. M3x3 brass inserts is optional part. It is needed for BLtouch mount. Optional, you can use nuts here. BL touch. I recommend original here. I was try few clones, it was lost money due to instability of measurement. Titan AERO extruder. I am using chinese clone, but it is compatible with E3D Titan AERO too. many other parts which is not listed Instructions to print Only p_front part need support material. Recomended filament are PETG except p_fanDuct and p_front which must be made from high-temparature resistant material (HTPETG or ABS) Nozzle 0.35 ~ 0.5mm. 4 perimeters. 5 bottom layers. 6 top layers. 25%~30% infill. Layer 0.2 ~ 0.25 mm what you like.
