About this 3D model

The four-point bed support was beginning irritate me. My T1 heater wires were also working towards inevitable fatigue or kapton/copper failure. So, I fixed both with one part. An M4 x 6 mm set screw is used to provide a leveling adjusment (McMaster PN 91313A139). I use a 32 mill sheet of FR4/G-10 (McMaster PN 8667K51) under my heater. This provides some thermal insulation, supports, and protects the heater and glass from the set screw stress. Something similar would also work. Look for companion bed corners too.
