I was running nearly empty on Crushed Red Peppers that had one of those flip lids, and was tearing off. I want to reuse the container, but wanted a cap. Thanks to gork having fusion 360 file for me to customize. My new crush red peppers actually has a cap with a sifter separated.

I made two models, one is loose fit, and the other is snug fit. Depending on how well your printer is calibrated, loose fit should be fine. I printed this on a trident using voron parts spec profile, which was 5 walls, 5 top, 5 bottom, 50% infill. YOU DONT NEED TO DO THAT. With this being a simple cap, choose what you want,
