Spring loaded 4 point level table

This bed was originally designed for a research project and mounted on a 30x30 extrusion. The top has been flattened so you can easily add structures on it, if needed. The 3mf file contains the spacer, a baseplate, the tabletop and 4 tensioners. (import as seperate objects!)All parts can be printed without supports. The spacer and tensioner include sacrificial bridge layers that have to be removed after printing. The M4 nuts may have to be inserted using heat. The following parts are needed for assembly, see drawing for instructions:M4x25 or M4x30 x4 (can be longer if paired with longer springs)M4x10 x2M4 nuts x 1010 mm Springs (if paired with M4x25 or M4x30)Optional: M4 washers x4 (in-between base and tensioner)I recommend using a rigid material, such as PLA for the base plate.
