[UPDATE May 2nd 2026] New version added that allows different sizes on each end and for each end to be ovaled rather than only perfectly round. 

A customisable connector for joining rubber and silicone intake/intercooler pipes. You can specify the elbow angle (or 0 for a straight connector), the inner diameter, thickness and size/number of barbs to be added etc.

If MarkerWorld's customizer isn't working, open the file in a recent (nightly) build of OpenScad and it should be fine. All of the customisable parameters are at the top of the file.

The included stl file is for example only.

As with any automotive print, be mindful of the material you print in as these can experience high temperatures when under the bonnet.

Material: PETG or CF is recommended
Layer Height: 0.2mm
Perimeters: At least 5 (6 recommended)
Infill: 40%-50%
