Thermolec furace humidifier overflow tube replacement

thingiverse

This Thermolec Furnace Humidifier overflow tube substitute is a 3D print replacement for the main part of your furnace's overflow assembly. It prevents water from spilling into your furnace by providing an overflow tube. The original plastic tube can easily break, so this redesigned print ensures stability and functionality. You will need an M12 x 1mm thread die to match the thread of the retaining nut or, alternatively, a 7/16 x 24 threads per inch die if needed. Adjustments may be required due to over-build or shrinkage issues. The tubing nipple is the weakest part but can be reinforced with larger tubing. Reuse the original rubber O-ring and finger-tighten the nut only. Original and printed tubes are shown in pictures for comparison.
