Nice mod! Anyone remixed top mount to enable supporting rails mid span? Fasten to rail using Remix of model part that’s normally inserted into z axis to help captive nut.
Edit: I ST*W and stumbled onto Remix of Customizable Jack Screw Top for Mid Span Support by GeoDave - Thingiverse and MPCNC leg leveler, stiffener and large table support by cmidgley - Thingiverse, these help prevent sagging. But, guessing welded/bolted solution would be needed to prevent lift and increase rigidity, for outer rails?
