There is a Patreon page at https://www.patreon.com/user?u=3753058
On this page I try to offer “products” that are spin-off effects of the development of Marlin3DprinterTool.
I try to keep the prices so low that nobody can say that I make this for money.
I am doing this for my passion for 3Dprinters
Other persons worth alot to the 3Dprinter World are:
Scott Lahteine is creating Marlin Firmware ( https://www.patreon.com/thinkyhead/posts )
Gina Häußge is creating OctoPrint ( https://www.patreon.com/foosel )
Without them and their development 3D printing should not be what it is today
SUPPORT THEM!!
