Just print it out and insert your sticks of ram and it should work just fine, it was designed with SODIMM RAM in mind, full size sticks of ram are slightly too tall, but it should be easy to scale it up 1.05x which should fit a full size stick. I didn't need glue for mine and the RAM is secure. The ram gets better grip on carpet but it does work on other floors. Other doorstops may hold the door a little more secure, but mine has better specs. I only printed the 35 degree version, but i uploaded some other angles for a choice. It takes about 25 minutes to print with no supports needed, and the RAM is surprisingly durable yet springy.
