Other TUSH

with the construction of my box for my CR10S, (https://www.thingiverse.com/thing:3331160) i decided to put the filament outside the box. i could use some other tush who wiould work perfectly, but i want to put the extruder motor outside, so, this tush is upper than all other to be able to put the motor between the tush and the trough wall (https://www.thingiverse.com/thing:3513901)

it's very stable with the arm between each side. need 4 ball bearing
