Version 2 update: Includes a new bracket model having a flat bottom and cut-out for a bottom knob. This can be used as a locking knob to both lock-in a level adjustment, and also keep the bed from lifting out or tilting. Requires at least a 25mm bolt to use the bottom knob (likely 30mm or more to allow for more than 1-2mm adjustment).
Designed to mount to the side of 2020 aluminum v-slot using M3 screws and support a glass or acrylic bed. Use mounting tape to attach the bed to the support ears (a thick rubbery double-sided tape, available at hardware stores).
Adjustable using the included knob for easy bed leveling.
Print three for a 3-point leveling mount. Press an M3 nut into the top of the knob and the bottom of the bed support piece, mount the brackets to the side of the V-slot under your bed with the flat side up (clean out the holes well, making sure an M3 screw slides freely up and down but without much wiggle).
Insert an M3 screw (25mm recommended) through the top of the bed support and tighten. Thread the knob onto the screw, and Insert the free end of the screw through the hole in the mounting bracket, then apply mounting tape and stick your bed down.
