Here is a E-22 print file for your 3D-Printer. I always wanted a E-22 for my 1/12 scale Shoretrooper.
I used the CAD-program Siemens NX 1953 which I use in my company. I can use the program also in my free time.
File format: STL (attached)
Scale: 1/18 up to 1/1 should work
I hope you like it and you can use it.
