The file 'Couch Coaster Extra-Large (Now For Bigger Couches) 3D Printer Model' is (skp,stl) file type, size is 1.2MB.
Update May 2020
If the girlfriend isn't happy, nobody's happy! I've created a double coaster for the bed, and a flatter coaster for less curved furniture.
I'm releasing a slightly larger version of the original Couch Coaster, modified based on real-world feedback. This one hugs the arm of the couch a little better and also offers rounded edges and a slightly deeper cup.
Still works with the three basic food groups: Coffee, Coke and Beer. Enjoy!
Update: I've uploaded a version of the XL which now includes ribs for your enjoyment. It provides a little better grip on cloth couches. Printed in brown and turned upside down, it also makes an attractive sushi dish. See Version-9 for details.
