+There are some different prints I'd like to acquire, but unfortunately
+not all, even used, are cheaper and easy to get.
+
+If you want to help funding money to get more printers or just want to
+donate because you like the project, please be in touch and I'll be
+sending my PayPal info so you can donate.
+
+Thank you!
