Amazing results with transitional filament. Sad about the warping but I'll redo it again, only hinders coin retrieval and maintenance.
Caution with warping when printing with PLA. Otherwise, don't over think it. Doesn't need supports, amazingly enough. I'd also recommend printing certain pieces like the latch, clips, front plate and flap at 98 or 99% and/or scaling up the main body to 101 or 102% just to reduce sanding and help with fitment. The other option would be remixing the remix with adjusted fitment but it's easy enough to just manually scale those parts to save yourself the trouble.
