I'm not sure if the license for Simpify3D allows me to install the program on two computers, one at home and one at work. I found tube holder for Flashforge Creator Pro on thingiverse, printed it, and installed it. The silver screws in the door hinges are supposed to keep the door open but is there a better way of keeping the door open? I have to buy Printbite surface for my new printer. Where can I buy it in USA?
