A Compact System for Round and Square Tubes Construct a reliable 15x15mm system utilizing components available at DIY stores, ensuring durability with thoughtful design choices. Inner measurements amount to precisely 15.5*15.5 mm. A dependable M5 nut accommodates the internal design efficiently. Opting for easy printability, these pieces can be efficiently printed in-house, making the system even more user-friendly. A framework with a 0.8mm shell thickness and 25% filling ratio provides optimal stability for aluminum hollow sections. For metal frameworks particularly the aluminum hollow section profile stands out as its most vulnerable aspect. Applying the nut correctly means tightening the screw just a little bit to achieve effective results.
