If you do print one with TPU, you may still want to do the panel piece in a more rigid plastic as it is very thin print. It will be real floppy in TPU. I’d try PLA and you should be able to bond it to the TPU bezel using cyanoacrylate superglue.
I designed a TPU bumper to fit around this more rigid case. I have added the file to the Printables model, but I have not tried it myself yet.
We fired the XR this afternoon for the first time. We had to fab a CPC torch on/off cable and it took us a while to figure out the wiring. The crossfire xl we had has a different connecter on the control box. All works perfect.
We used the XR cut some plates to weld into the corners as stiffeners. I hope to get them welded in tomorrow. We tigged the water table together yesterday and its ready to go on.
