To reduce the size of an STL file:
- Import mesh into meshlab.
- Go to Filters > Remeshing, simplification and construction > Quadratic edge collapse decimation.
- Cut the number of triangles by 50% (enter 0.5 in dialog box) as a first cut.

Temperature settings, common materials:
Note: these are good places to start in the absence of other information. If your manufacturer and/or the filament manufacturer used something different, start with their suggestions.
- PLA: Extruder temperature 210 degrees.
If you have an unheated platform, print on blue tape or glue stick (never heat a platform with blue tape on it). If you have a heated bed, bed temperature 60 degrees.
- PETG: Extruder temperature 220-260 degrees, higher temperatures typically produce a shinier appearance, lower more matte (note: you need a nozzle that can handle a temperature this high).
If you have an unheated platform, print on blue tape or glue stick (never heat a platform with blue tape on it higher than about 30C). If you have a heated bed, bed temperature 60 degrees. Do not print directly on PEI/Ultem surfaces, as it may stick permanently.
- ABS: Extruder temperature 230-260 degrees (note: you need a nozzle that can handle a temperature this high).
Heated bed is essential. Bed temperature 110 degrees.
Fixing a clog: search for “cold pull” or “atomic pull” for your 3D printer, or use this guide: http://bukobot.com/nozzle-cleaning/.
