This is my largest print to date with my Elegoo CC2. The diameter of the dew shield takes up just about all the available build plate. It's also about 170mm tall and took about 5.5 hours to print. The j-slots are based on the telescope stock lens cap, I made a couple of prototypes without the long shield to get that slot dialed in.

All and all I'm pretty happy with how it turned out. I need to work on the j-slots a bit. They are too flimsy and I need to thicken the material behind them and maybe make the portion of the shield that slips into the scope a bit deeper. Once I get that, I'll probably print the shield itself a bit longer. I think I can do 210 mm without pushing it.

This was also my first build using the Frostbite plate. I printed at a bed temp of 40 deg since the plate recommends between 30-50 degrees. It also printed a brim at the bottom for the supports and I see the instruction sheet for the Frostbite says not to use a brim. It was a large enough build that once everything had cooled off for a few minutes I could just give the plate a slight bend and everything just popped off. This was particularly satisfying because I'd been having some adhesion issues with the stock Elegoo plate.
