Glass Bed Holders for Wanhao Duplicator i3

These parts hold a 213x200mm glass build plate on my Duplicator i3. I designed them to flex a little, so that they will hold the plate snugly even as the aluminum of the heated bed slightly expands and contracts.

To install, remove the thumb nuts used to level the bed. Then, loosen the screws in the four corners of the bed, allowing for a few millimeters of vertical movement. Slip on the plate holders, with the broad sides facing the front and back of the printer. Finally, tighten the screws
