6. Donations
|
||||
|
||||
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!
