super cool profile. I made adjustment. added stabilization for ams hub and updated your model with tread for pc4-m6 and guide. it's a little to high now but will yest it and modify if needed.

Nice print profile, no issue at all with printing. Only i believe you need to modify lover part connection. add extra 2 screws. after assembly lover part moves up and down on the front. I added tape and its much better. Also please remember about using grease (the same as for feed screw) for TPU filament - its helping a lot. I will try to use regular oring but i found only 49x2 and 21x2 (originally should be 49.250x1.75 and 21.150x1.75) - will try and see. Original belt printed from tpu after 2 days started to rub and split. But here i believe my printer is an issue (i printed first time from TPU)
