SummaryThe Alibre model is parametric, allowing you to size it to exactly fit your particular 3d printer's table. It is sized to fit my Up! It is designed to be rigid, resisting curling at the corners, while using a minimal amount of material.InstructionsSize it to fit your printer's table, and print one out. Use it as a size reference when thinking about what you can make with your printer. Use it to test your printer on large items. I found that the corners curled off of the table some, and there were some splits in the corners partway up the sides. Good to find out before printing something more important.
