Electric duct junction reducer

This is a remix from the work of Phiphila https://www.thingiverse.com/thing:5974177This version allows you to connect a 1/2 to 3/4 (16mm to 20mm) electrical duct ICTA. IMPORTANT WARNING REGARDING THE USE OF THIS ICTA CONDUIT COUPLINGPlease read this warning carefully before printing and using this model.This coupling for ICTA (Insulating Cintrable Transversally Annulated) conduits has been designed for personal and experimental use, aiming to offer a mechanical connection solution.FIRE SAFETY CONCERN AND NON-COMPLIANCE WITH ELECTRICAL STANDARDS:Material: This model is intended to be 3D printed using PLA (Polylactic Acid). PLA is a combustible and non-self-extinguishing material. It can burn if exposed to a heat source or flame.Non-Compliance with Standards: ICTA conduits are self-extinguishing and flame-retardant, as required by electrical installation standards. The use of this PLA coupling, even if it ensures a mechanical joint, compromises the installation's compliance with fire
