I design primarily functional prints and holders, which is why i prefer PETG. I started printing with a delta machine, but it was very underwhelming. Next was an Ender 3 Pro with a Duet2 Maestro. Then I built myself a custom machine with Hermera Extruder and 4 independent Z axes (because I hate doing manual leveling) and a Duet3, but it it developed a slack joint and doesn't work for now. Then I got myself an Elegoo Mars Pro for cheap. Now I switched to an A1 Combo (my 5th 3D Printer now) and it's just amazing!
