Hi, all. So my first ever 3D printer is on its way to me. I went with an Elegoo Centauri Carbon, partially for the option of using OpenCentauri firmware. I have been looking at various models on printables.com and Thingiverse, getting excited for the possibilities. I would just like to ask if there are any big pitfalls I should look out for as I'm starting my 3D printing adventure. What mistakes did you make when you were just starting out? What resources do you wish you were aware of earlier? What general advice can you give me?

Thanks in advance, and have a lovely day.

Watch out for overhangs on models. Every feature needs a surface to print on.

Also, probably not such a thing anymore, but give some time to get to know your printer before doing mods to it. It's near impossible to troubleshoot issues when you dont know whether the issue is caused by a defect with a new printer or something caused by a modification.

Keep your filament stored in something whether it be ziploc bags or those fancy filament storage containers. Also get some desiccant and hygrometers so you can actually dry and measure. I have found the desiccant bags to be pretty worthless while the little colored or white balls/pellets work well and can be recharged.
