I designed these parts to mount linear guide rails on the Y axis of my Elegoo Neptune 3. This kit could be used for any 235x235 machine with 4040 Y axis extrusion.
The linear rail adapter is universal left and right, which is why it's shaped the way it is. You need 2 adapters and 2 jigs. The jigs use the same M3 x 8mm screws and T nuts as the rails, so everything can be done with basically one screw size. You need 4 M5x16mm long screws to mount the adapters to the bottom of the table. Leave them loose until you secure the adapters to the linear trucks with the M3 x 8mm screws so the adapters are mounted securely to the trucks, then adjust and tighten the 4 M5 lock nuts to secure the table. The jigs are used on the underside of the 4040 extrusion to align and center the rails.

This kit took a long time to design, test, revise and implement, so if you wouldn't mind, drop me a tip! :)
