allows you to interact with all your printers via the Cloud, and many other exciting new features.
The one above was made in PLA.
I made on a red one in nGen but it axles expanded so much it did not fit.
The tracks are so large that they do not fit on my print plate. ;-(
Thanks for sharing the images! Looks nice!
