Brittleness might be a concern, it will be for a costume piece

Thank you!

I haven’t had boxed Mac and cheese in a while, usually Costco’s premade is a favorite at parties so I have also given up trying to make Mac and cheese myself.

Cracker Barrel and the Walmart brand equivalent have been my family’s favorite for the rare occasion where we make boxed Mac and cheese. I grew up with Kraft, but now it makes me feel sick for a while after. I tried the Cheetos one with some friends once when it was new, expecting it to be terrible, and it really upset our stomachs, I was also pretty grossed out at how neon orange it was.

I live in a really dry climate, so I don’t really notice issues unless I have a spool out on the printer for months, and even then dust is more of an issue than humidity.

To be safe, I bought a storage bin with a gasket on the lid that I store all of my other spools in, and that has seemed to work great.

I saw someone else also suggest it, you could do an automatic fire extinguisher.

This one dispenses after 3-5 seconds of direct flame contact, others will be different.

I have been working on costume parts, my process with split pieces is first assemble with painter’s tape to get a test fit, disassemble, super glue the pieces together with locktite gel control, sand with 80 and then 220 grit, paint with rustoleum 2-in-1 sandable filler, fill in gaps and seams with bondo glazing spot putty, sand the entire thing with 220, and then repeat paint-bondo-sand until I am happy with the surface before I move onto actually painting.

Basically this process.

If I don’t want to paint something, and don’t care too much about layer lines, I’ll usually use super glue and then a wood burner to melt the edges together. It isn’t the prettiest, but it works fine.

I have had 100% success sealing PLA prints used as plant pots (I know OP is asking about PETG, should still work) with a can of rustoleum spray lacquer, much easier than trying to dial in settings.
