Not sure why it would warp there, perhaps infill percentage is too high?
If you don't need the layer lines to be in a specific orientation I'd consider rotating the model back 90° for the reprint, hopefully that should avoid any warping.
I never hade Twitter or the likes so I don't really interact with those types of apps all too often, but I have a Mastodon and a Pixelfed that I look at every once in a while. Also recently got a Loops account that I have barely opened.
Always nice to have an account set up and ready if I feel like using them in the future
What software are you using? Do you have any experience using any CAD-program?
