15x15 mm junction 3x for square round tubes aluminium profile

thingiverse

Users can print a robust 15x15mm system for square round tubes using items from a DIY store. The interior dimensions are exactly 15.5 * 15.5 millimeters in size. A M5 nut fits snugly inside it, securely holding everything together with ease. Anyone with basic knowledge of 3D printing will find this project easily printable, thanks to its uncomplicated design and generous layer thicknesses that provide enough structural integrity without requiring excessive resources or expertise. For those working with aluminum hollow section profiles however, this is where things become problematic as the screws tend to slip due to inadequate holding power causing parts to shift prematurely when tightened too tightly resulting in reduced system accuracy over time especially when dealing with critical systems where minimal movement means everything so be very careful when adjusting your framework or risk damaging important components.
