Project 220320 - a structure with 4 frames build with T-Track 2020 using FREECAD software

This is a FIX-COST project Project 220320 - a structure with 4 frames build with T-Track 2020 using FREECAD software 1. This cad files of the objects (Subparts) are 300 bpi a. The t-track 2020 object is a standard aluminum extrusion. (a CAD file is provided) The object HxWxL is 20x20xL mm and it can be changed by changing the HxW size to 25,30, or 40mm standard available sizes of T-track. This is a subpart of all 4 frames in the structure. b. The FRAME1 is an object with HxWxL is 154X50 cm and it uses the T-Track 2020 subpart. The HxW of the frame can be changed by changing the length of the subpart t-track. (FRAM1 is 2 T-track 2020 of 150cm and 2 T-track 2020 of 50 cm.)
