Heated Build platform Coupling.

thingiverse

To avoid clamp scraping, I designed a build platform coupling that wraps around your heated bed and 3mm-thick glass. The coupling features two full build plates – one with rail supports for printers with long bridge issues, while the other lacks these supports. Individual sections are also included to replace broken parts without reprinting the entire item. However, be cautious when installing or using this item since it's made of PLA and can warp at ABS temperatures. This concept is a work in progress, so please print at your own risk. Share photos if you make one, suggestions are welcome, and expect design changes. Updates include thicker rails, through holes for heated bed mount screws, and additional supports in the models. An version without supports will also be available for Slic3r or skeinforge to generate them.
