Z Axis FlSun Leadscrew Bearing Support
Description
Because I wanted to replace the original leadscrews (320mm) with longer ones I needed something to support the other end of the leadscrews: https://www.thingiverse.com/thing:2552986 Found nothing to keep it at exact tolerances and sturdy enough (This design https://www.thingiverse.com/thing:2831543 comes close, but it doesn't prevent user error) This design replaces the L-shape bracket and provides exact distances as the motor mount above. Plus it is stable on all 3 axes and is torque resistant. Designed from 0 in Fusion 360 using the exact distances found in the motor mount. I first imported the top motor mounts stl, to measure them more precisely and left enough room for brackets to go on the outside: https://www.thingiverse.com/thing:98234 Edit 2018-11-14: I had to trim the T8 rods down to 380mm to fit exactly between the top motor coupler and the bottom support bearing. Another good thing I found is this https://www.thingiverse.com/thing:2350350 which can be inserted just under the coupler. Additional note: The only play now is the actual coupler which flexes in the z (up-down) direction. I plan to swap for this https://www.aliexpress.com/item/UXCELL-5mm-to-8mm-Inner-Dia-Rotatable-Universal-Steering-Shaft-U-Joint-Coupler-for-Connect-Motor/32900293107.html or this https://www.banggood.com/5mm-8mm-Shaft-Coupling-Rigid-Coupler-Motor-Connector-With-Spanner-p-1070710.html Edit 2020-03-22: Lowering the overall height so that the V-Slot Bearing Wheels have more room.
