Printable parts for the CoreXY Frame based on FABtotum's concept without crossing belts. Prototype: Not tested. Version 2.1 designed for 5mm slot 2020 extrusion: https://www.thingiverse.com/thing:2266282 Extruder mount: Titan: https://www.thingiverse.com/thing:2253311 Custom: https://www.thingiverse.com/thing:2664121 Laser: https://www.thingiverse.com/thing:2685298 CAD: https://grabcad.com/library/corexy-frame-v-2-0-1 Version 1.0: http://www.thingiverse.com/thing:1811983 Search for a 20x20 aluminum profile with a 6mm slot for a 5mm slot version 2.1 in my Things. Use MGN12 linear rail 3 pieces plus MGN12-H/C carriage block 3 pieces (Reference link: http://ali.pub/vnk2s). For MGN9 rail, use "v2_X_bot_plate_MGN9_LR.STL". GT2 6mm belt lengths depend on the desired work area - calculations can be found in the picture. Use 2 GT2 pulleys with 20 teeth each. F694ZZ ball bearings are required in quantities of 16. Four 2020 internal L-joints and four countersunk M4 screws (40mm long for gantry) are also needed. Additionally, use ten buttontop M4 screws (10mm long), two socketcap M4 screws (30mm long), two M4 washers (0.5mm thick), eight M4 Nuts, and eight 10mm buttontop M3 screws (for NEMA17 motors) and six mm buttontop M3 screws (for MGN12H linear rail). Two pins are also required: 26mm long x 4mm diameter. These can be found by using a 26mm M4 screw with the head removed or 26mm pieces of 4mm welding electrode without coating material. Alternatively, use 26mm pieces of alloy steel dowel rods available on Amazon at https://www.amazon.com/26mm-6325-Dowel-Alloy-Steel/dp/B01I0BDG06 Many thanks to Turner Hayes for the bill-of-materials list located at http://www.thingiverse.com/tomasro/.
