Rainproof Terminal Vent Duct – Clamp-On Visor

This rainproof terminal is designed for the top end of  14.4 cm ventilation ducts, offering both protection and simplicity. The piece functions like a clamp or collar that wraps around the duct's edge, with a thin, curved visor extending outward to prevent rain from entering. The design consists of two interlocking parts: the main clamp and the overhanging visor, which is printed separately to allow a fast and support-free 3D print. The visor is very thin and flexible, so it can be slightly bent and inserted into a dedicated slot in the clamp piece. Depending on your printer’s calibration, the fit may vary; if the parts do not snap perfectly, it’s recommended to assemble them and then gently apply a lighter’s flame to the back, fusing the two components together. This design prioritizes ease of printing, minimal material use, and fast assembly—ideal for functional prints that need to be weather-resistant without requiring supports.

Note on material:
Do not print this in regular PLA — even a single day of sun exposure can warp and deform the parts. For best results, use ABS+ or PETG, which offer much better heat and UV resistance. If you're using an open printer like the A1 Mini, PETG is highly recommended for consistent outdoor performance without warping.
