This is a linear rail mounting system for the Adimlab Gantry-S printer. This uses the Adimlab x carriage plate so you can keep the original hotend if desired. Use a 300mm MGN12H linear rail. You may also need a new belt. An x-axis belt tensioner is highly recommended.
Hardware:
3mm threaded inserts for the 2020 rail brackets on the top to mount the linear rail
5mm pan head screws to mount the 2020 rail brackets to the front of the 2020 rail
5mm threaded inserts to mount the OEM x-axis plate to the rail bracket
3 mm screw to mount onto the linear rail shuttle
Either a threaded insert or a screw and nut to mount the belt bracket adapter
