An adapter to fix silicon tubing to a container e.g. plastic canister

The plug is sealed by an O-ring and countered by a nut (can be hand-tightened)

The STL files in the upload should work for 4mm - 5mm inner diameter tubing and a 10mm drill hole in the container. The O-ring used has 15mm outter diameter and 2.5mm cross-section diameter. Parameters ca be set to fit your equipment etc

Feel free to download the FreeCAD file and edit the parameters to your need.

Best print in PETG. Plug 100% infill, Nut 30% infill Seam position random to get a more homogenous thread.
