FLSUN Cube to CoreXY

[v1.6]-[15-10-2019] I designed two adjustable steppermounts, making it easier to adjust tension in the belt-system. This is achieved with a large M8 screw pushing against the stepper. A knob will be added later that can attach directly onto the screw-head. Additional requirements include four pulleys (two with teeth and two without). Mounting to the frame uses M4 bolts; pulleys use an M5 bolt. [v1.0]-[04-10-2019] Firstly, this is Version 1 of my CoreXY conversion build and my initial attempt. Some parts require a complete overhaul. My part cooler is my first-ever creation in Fusion 360, a fang cooler design. Real-life results are disappointing (the fang is too close to the hotend). I'm redesigning it now. Currently, stepper mounts are non-adjustable; I'm designing new ones for belt-tensioning. These will be posted in a future update. For now, my unofficial Bill of Materials includes: - 3* 400mm MGN12H rails - 1* 400mm 2020 extrusion - 5m belt - Pulleys (when using the adjustable stepper-mount) * 8*20t pulley (M5 bore) * 4*blank pulley (M5 bore) - Bolts: * 10*M5x50 * 4*M5x40 (for the XY connectors) * 50*M4x10 (used to bolt down all the corner-stuff) * 50*M4 T-nut to bolt everything to the frame * 100*M3x8 for the rails * 100*M3 T-nut to bolt everything to the frame * 25*M3x10 to attach the carriage to the rails More bolts will probably be needed, but ordering smart from Aliexpress won't break the bank. The XY-Cap needs to be printed twice; it fits on both sides. Mounting materials: - M5*50 bolts for the wheelhouses and XY connectors - All frame-mounting is with M4 - The hotend-mount is mounted with M3 bolts Stepper-mounts and wheelhouses serve as frame-corners, so they're printed heavily for strength. I used 0.2 layer height with a 0.4mm nozzle to print everything. My build was greatly inspired by LordKyleOfEarth's design (https://www.thingiverse.com/thing:3094320), but I was stubborn and wanted to design it myself.
