This is a heated bed bracket for the acrylic geeetech prusa i3 to be laser cut, routered, machined, or printed if you have the size. Bed bolt hole to hole is 209mm, bearing brackets are 24x18mm. Mine broke and Geeetech wouldn't send file or provide replacement to buy so here we are, hope it fits good, haven't made one yet. Holes are 4.1 and 3.1mm, may need reeming to size. Enjoy and comment with issues or cheers please. Included 10mm and 7.4mm thick versions, original is 7.4 but thicker would be stronger and also allow you to use Z wobble eliminators easier.
