SnapMaker U1 rear gasket Shim

This flat gasket (shim) mounts between extruder 2 and 3 at the rear of the unit around the top lid connector (see photos). It closes a potential leakage there between the lid gasket and the printer. Not everyone will need it, but I did (along with the feet that I published here and shared with Snapmaker R&D, who have now published their version here:

Print with TPU (I used Gizmodorks TPU with the generic TPU settings), use a sufficiently thin layer height so you get the wings (which will mount under the screw holes of the extruder connectors 2 and 3 (see photo).

Happy printing (with less leaks)!
