Steel Spring Glass Hotbed Corner Clip for Anet A8 or A6

thingiverse

I recently acquired a glass hotbed plate for my Anet A6 3D printer. I've been using Exsilium's adjustable corner clip set, which is an excellent modification of thfo's original design. This setup has worked flawlessly so far. However, when printing with 3D Solutech PLA and performing large-volume prints, the prolonged heat exposure from the hotbed has caused a significant issue - the spring corner has lost its tension, allowing the glass to become increasingly loose. I appreciate the no-screw tension fit design of the original clips, but replacing worn-out components requires re-leveling the bed, which is an inconvenience I'd rather avoid. Therefore, I modified the design to utilize a strip of spring steel cut from a sliding-door roller unit with approximately 0.7mm thickness. This material provides the necessary rigidity and durability for a long-lasting corner spring. Printing this part takes mere minutes, followed by a few minutes of work with a rotary tool and a cutoff wheel, resulting in a robust corner spring that can withstand repeated exposure to bed heat without deforming quickly.
