A mod to convert standard split doors on most voron models to a sliding method. This version is for the 300mm version and you can use F623 623 or 693 bearings for the bottom roller. Use 2 3mm washers per bearing. Print and install the bottom. Measure from the top of the door to the top of the extrusion and print the closest height to measured distance. Should be reasonably tight to ensure the door stays in as expected.
