I just received the UM2+ upgrade and realize that I'm going to be removing the original UM2 print head for the UM2+ head.   I also happen to have a thoroughly hacked/modded UM original-original machine. Has anyone come up with a hack/mod to refit the UM2 head into the UM original-original Machine?   Perhaps  a printed replacement of the wood enclosure which allows the larger UM original rods, but permits the UM2 heater/head assembly to screw on? Thoughts? *B
