Printing config

I print these fitting with PETG (I use PETG from Nanovia, but any PETG should be fine). With 100% infill. Always print vertically. Depending of the combination of sizes, it can be a good idee to rotate upside down the model in the slicer.

File Naming Convention Description

Each file name follows a structured format designed to encode both the technical configuration of the fitting and a human-readable identifier, separated by a double underscore (__)separated by a double underscore (__).
Example:

20sF_03fF__G2_1-2_SwiFemale_to_G_3-8_FixFemale.3mf

• The first part (20sF_03fF) encodes the connection details in a compact, machine-readable form. This section is composed of two subcodes, one for each end of the fitting, separated by an underscore. Each subcode indicate:
  • Numeric Prefix (size in eighths). Example 20 means 20/8=2+½, then G2 ½.
  • Connection type:
    • M → Male
    • fF → Fixed Female
    • sF → Swivel Female
    • Stop → End termination without size (plug)
• The second part (G2_1-2_SwiFemale_to_G_3-8_FixFemale) provides a simplified, human-readable description using the same information. Spaces are substituted by _, and / by -. For example G2_1-2_SwiFemale_to_G_3-8_FixFemale means Swivel Female G2 1/2 to Fixed Female G3/8.
