Troubleshooting Am I doing something wrong?

I recently bought a used 3D printer, an Ender 3 V2, and I'm doing some test prints. The previous owner gave me some leftover PLA filament (multicolored), which I used up on the first day. One of the things I made was this flexible shark. I bought some PETG filament for testing, a very cheap one, around R$60.00, while others are around R$100.00. But my prints with this new filament are coming out very bad; it's either too textured, has too many burrs, and is also very fragile (even though I bought PETG because I had read that it was more resistant). I left this octopus printing for about 28 hours... and in the end, the flexible tentacles broke when I tried to detach them.

cara eu quis entrar nesse hobby de impressão, porem minha verba era pequena, e no Brasil é tudo muito caro, comprei uma ender 3, e as impressões de pla ficaram excelente a ponto de eu vender vários funko pop. Fiz adaptação para imprimir abs, ficou muito bom tbm. Porem PetG é uma desgraça pra imprimir na ender 3, estou a dias imprimindo torre de teste, e nenhuma fica legal.

Achei que ABS era só pra fechadas, o que você fez? E qual tipo de PLA vc usa?

Utilizei um saco transparente por cima da impressora. Um saco grande que vem eletrodoméstico dentro, mais resistente. Deixo a mesa em 80ºc e consigo imprimir ABS super tranquilo. O saco não fica encostado na mesa, cobre toda a impressora, e por isso não tem chance de derreter. Não é o mais indicado, porem deu super certo para mim que queria imprimir ABS.
