This is a mod of SuperSniffle's 4028 Backplate for the EVA carriage system.
All credit goes to SuperSniffles, for the original model, and Pawel Kucmus, for his awesome work on the EVA system.
I simply modded the original file to fit Cartesian printers, such as the RatRig V-minion.
This mod also uses heat inserts, instead of captive nuts.
Compatible ducts for this mod can be found here. (note: this mod uses two additional air ports, so is incompatible with standard EVA ducts)
THIS MODEL IS CURRENTLY UNTESTED, PRINT AT YOUR OWN RISK.
I hope to test this soon, but see no reason why it shouldn't work. Feedback welcome.
