I’ve also had problems with PLA prints delaminating and becoming brittle over time, especially if it’s being flexed or exposed to sunlight. Some PLA’s are worse than others with this, though.

I use PETG for anything I want to last a long time.

I think I’d recommend either buying a larger prusa printer, or a cheaper starter printer. The mini has a small bed that you will probably want to upgrade at some point.

You can regularly find an Ender 3 for ~$100. It is one of the most used printers out there. Tons of information available online about them. You won’t feel bad about wasting a bunch of money on a printer that sits unused.

I bought the Prusa Mk3s+ as my first printer, but I wish I had gone with something cheaper. I didn’t know what I wanted because I hadn’t had a 3d printer yet. Now I really want to build a Voron, but I can’t justify retiring a perfectly good $800 printer to build a new one that’s faster.
