CNC remix 16mm rods from art_and_tech and NikodemBartnik

Update: 1/07/2020 I discovered issues with the 2020 crossbar and how it attaches to the drag chain, which prompted me to repair those files but leave them untested for now. I uploaded revised files featuring a redesigned 2020 crossbar as well as files without the crossbar at all; if you encounter any issues, please report them so I can make necessary repairs. Regularly check back for updates. Thank You! Warning: This is still a work in progress, although I'm pleased with the design at this stage; however, I may make changes or adjustments based on feedback. I welcome and appreciate constructive criticism to help refine the design. I was inspired by the MPCNC designs and came across NikodemBartnik's impressive creation, https://www.thingiverse.com/thing:3004773, which led me to watch his videos showcasing the abuse he subjected his 3D printed CNC machine to. After researching further, I found art_and_tech's remix, https://www.thingiverse.com/thing:3750446, of NikodemBartnik's design and was even more impressed by the attention to detail added to an already excellent design. Wanting a bigger CNC, I decided to increase the x-axis to 600mm using 12mm shafts but opted for larger 16mm x 800mm LM16UU bearings on the Y-axis due to concerns about stability with heavier gantries. I added a spot on the XY mounts for a 2020 extrusion to enhance stability and provide a secure path for the cable drag chain. Considered a novice, I appreciate constructive feedback and encourage you to share your thoughts. This design was created in Tinkercad; if you're interested in accessing it, try sharing the files on Tinkercad. Initially printed with PETG, but due to multiple changes along the way, I switched to ABS when my PETG supply ran out; both materials seem to work well. This is a remix of other designs and requires x-axis parts from those original sources. I'd like to extend gratitude to NikodemBartnik and art_and_tech for their exceptional work, which deserves recognition; please visit their pages as they've done an outstanding job!
