T-slot 2040 extrusion cnc gantry using 608 bearings (WIP)

thingiverse

This is a "use what I have project during isolation CNC". It utilizes 608 skateboard bearings and 8mm rods throughout its design. Engineered to operate on 2040 t-slot extrusions with the small 7mm lip in the track, as illustrated by the cross-section image. This design should also accommodate v-slot extrusions with v wheels, although this has not been thoroughly verified. There is a considerable amount of travel in the tensioning arms. The size of this project can be scaled to its limits, depending on the available t-slot extrusion. The remainder of the parts were salvaged from an Anet A8 3D printer.
