Corner Bracket glass plate Wanhao i3 Plus

Update on 4/10/2017: Use the new Corner_Bracket_v2.3.stl file. From much testing and use of my iterations on this bracket, I have found that additional strengthening was needed to prevent the bolts from bending the bracket outward when tightening up against the glass plate. This version has a thicker cross bar and the corners where the bolts are placed now continue down to fully meet the crossbar. I also moved the hole for the M3 bolt to better align with the heat bed (no more carving with a X-Acto knife). I also lowered the height of the retainer clips (holding the glass) as they were interfering with the homing of the extruder tip.This version has all the changes made to date.

This remix adapts the design for a Wanhao i3 from Webberen

This one is specifically for a Wanhao i3 Plus (may also work on a Monoprice Maker Select Plus). I found that my built/heat plate and borosilicate glass were both thicker than allowed for in his design. I also had to move the mounting hole for the M3 bolt to match that for a i3 Plus build plate. I made the clips to hold the glass a little longer as I did not have M3 bolts longer that 18mm.
