Hand-Tightening Rings for 6-30mm Hex Nuts

[Update 2025-01-13]
In response to popular demand, I've added hand-tightening rings for 6–30mm hex nuts in 0.5mm increments! This new feature enhances usability and offers even greater versatility for your projects. In total there are 49 new plates to print, all with optimized, strong profile settings!

This 3D model is a functional tool, designed to facilitate the manual tightening of the LPG tube adapter for RVs. The tool features a 52mm wide ring with an ergonomic grip pattern, ensuring ease of use. The central hexagon hole is 24.5mm, fitting securely over the LPG tube connector. Additionally, the design includes two 2.5mm diameter holes that can be tapped with a 3-5mm diameter tap, allowing for the insertion of stop screws to secure the tool in place. This model aims to provide a practical solution for those needing an easier way to tighten LPG connections by hand.
