This is my New designed 3D printer, the name is ARegoCW Tximy3D2 and the structure is 2020 aluminum T profile, all axis are trapezoidal screw design and I use a 2GT timing belt to synchronous multi nema axis to prevent lost steps and power the accuracy and performance. It is under development.
The V36 updated the Y axis optical end stop support and flag, the v43 upgrade X axis optical endstop and flag without screw.
The printer are working fine ;)
1 x lead screw 580mm for X axis
2 x lead screw 500mm for Y axis
2 x lead screw 500mm for Z motors axis
1 x lead screw 540mm for Z rear axis
Total: 4 x 500mm, 1x 600mm, 1x 550mm. and 6 x lead screw nuts
12 x 500mm 20x20 aluminium T profile
2 x 500x8mm rods for X axis
4 x KP08 for 3 Z axis
2 x KFL08 for X axis
4 x 20 teeth 8mm bore 2GT pulley, one for X axis lead screw and three for Z axis lead screws
1 x 20 teeth 5mm bore 2GT pulley for X axis motor
2 x 16 teeth 5mm bore 2GT pulley for Y axis synchronise
1 x 98 2GT-6 belt
4 x 5mm to 8mm bore adapter, two for Z motors axis and two for Y axis
4 x LM8UU bearing for the X axis carriage
many M5 screws, hex nuts and T profile nuts
Hotbed installed and working fine https://www.youtube.com/watch?v=KVMgn-SZig4
Cold bed print try, and working Ok https://youtu.be/r5hEbrAJJU0
V44 incorpore support and fixations for Z axis, and many parts are coming soon.
V55 the printed parts are finished.

All axis working https://youtu.be/z23VY4WnKQA
I use T8 8mm screw length 1000mm picth 2mm lead 12mm trapezoidal screw with brass copper nut for optimize speed.
I am working too at external case : http://www.thingiverse.com/thing:2308911
The X axis motor mount are damaged by the intensive use, the redesigned replacement is EjeXIzdaV58.stl
The new electronic enclosure for Arduino DUE, Ramps-FD. 6x Tl-Smoothers, OrangePi PC for OctoPrint and more ;) with an internal 120 mm fan https://www.thingiverse.com/thing:2452202
