Vacuum Table Pyramid Spacers

Pyramid spacers for a CNC table vacuum. Pyramids are 2cm tall to match the height of 2020 aluminum extrusion used to build the table of the CNC machine. Four of these were printed in order to fill out the space the vacuum portion of the table was intended for; they provide support to the MDF above them in order to prevent the surface of the table from bowing inward when the suction is on.
