120mm round 3mm thick borosilicate glass plate. This was once designed to work with Monoprice MP Mini Delta, but will even work with any small delta printer than can use a 120mm diameter build area. Borosilicate glass plates are ideally suited to be used with 3D printers because they’re naturally flat and immune to thermal shock and warp that may impact other varieties of glass.
120mm round 3mm thick 100% Borosilicate glass plate
Low thermal expansion and immune to thermal shock
Very flat surface for 3D printing
Great fit on Monoprice MP Mini Delta, quite over sized to permit for quick alignment
