  • How would I split this model in Cura? (More details below)
    I split my Boba Fett helmet STL in Slic3r. It was incredibly easy to split the file into 8 parts. The top and bottom halves split at the visor line, then split those pieces into halves and then halves again so they will fit on the bed. Source: almost 3 years ago
  • What? Brim printed fine, but why is it doing this? Using Hatchbox PLA at 210 nozzle temp and 70 bed temp on an Ender 5 Plus. I'm using the Creality Slicer that came with
    Try using a diffent slicer. Either cura or slic3r. Source: over 3 years ago
  • tesla turbine style fan blade.
    I use Slic3r where the preview is quite easy to get, but the configuration might be a bit scary to get done (although the defaults are reasonable) as you want to try with adding or removing support material. Source: almost 4 years ago
