Sharing designs isn’t as easy as it could be and I’m working on a solution. It’s still very much a work in progress, but when Create is finished you will be able to share designs with a link like this:
https://maslowcreate.org/run/?182022403
Note that you can edit any of the height, thickness…etc parameters on the left. Soon there will be a “download gcode” button over there which will give you a file that is ready to cut.
