This is a 1x1 insert to hold the small model needed to plot a full 256x256x256 print on the X1 or P1 series because I knew I'd lose this if I didn't have a home for it. If you need the part, there is a link to download it here: https://wiki.bambulab.com/en/knowledge-sharing/print-volume-limitations.
I see now why people say figuring out new models eats up a lot of filament. So if you'd like to buy me a cup of coffee or, more likely, contribute toward another roll of filament you can Paypal me here. Thank you!
This is based on the empty insert boxes by Willi 3D.
