Tired of prints sticking too much or not enough? Upgrade your 3D printer's build surface with this 3-pack of borosilicate glass plates. Each plate is 6 inches by 9 inches (150mm x 230mm), a common size for printers like the Flashforge Replicator series. Borosilicate glass (like Pyrex) is great because it heats evenly, resists thermal shock, and gives you a super smooth first layer. The brand is GO-3D PRINT (MPN GP 6X9C). Made in the USA. Having a 3-pack is awesome – you can have one on the printer, one cooling with a finished print, and a clean spare ready to go. Just clip it onto your existing heated bed. Improves print adhesion and bottom surface finish dramatically. An essential upgrade for serious printing.
