Sometimes after I finish a print I know I’m going to print something else in a few minutes. In those cases I want to keep the heater warm rather than waiting to cool it down, warm it back up, and then start printing. Here’s my new idea – I use the in between print time to print something quick, simple, useful, and relatively worry-free.
Insulator retainer rings. I’m guessing you just can’t have too many of these. As suggested by Cathal Garvey, this should be a high priority print.
