About this 3D model

This model is essentially an improved version of the previous one . To assemble this model, you will need a HEX head M4*20 BOLT & 2 nuts Boost Me If you like my work and want to support me, a Boost is greatly appreciated! [how to assemble] 1.Set the bolts in the top parts. HEX head bolt will fit into the recesses. 2. Set the middle parts and the nuts. The nuts will fit into the recesses. (Tighten them to a certain extent at this point). 3. Mount it on the rail. Hold the bolt and rotate it. 4. Hold the bolt and tighten the nut to fix it to the rail. 5. Finally, tighten the hook and the nut to complete the assembly. [Note] The width of the top parts is 15mm. There must be enough room within the rail for these parts to rotate. By changing the length of the BOLT, it is also possible to accommodate thicker rails.
