Our insulator retainer acrylic part broke when we hit a blob of plastic. I was able to glue it back together but think it is a good idea to have an extra one around.

OK, the acrylic part just shattered, so I installed the printed part and it is working great!

I was concerned that the insulator may get too hot for an ABS part, but after several hours of operations at 220 degrees, it is working fine.
