Hergo Rack pegs
thingiverse
I created a remix in FreeCad using 3D printed pegs to hang various items from a Hergo Tech Lab computer rack. I was unsure if it could be used with other manufacturers' racks, but the quickest way to test would be to print the Hergo shelf DIN rail adapter by N1VG for a fit test. I imported that project into FreeCad as an STL and then converted it to an object where I added the peg to hang things off of. Given the peg design, it would not support much weight. You are free to use FreeCad and export it as a step file to the designer of your choice and add supports for more weighty objects. However, it is simple to make changes in the "Part" workbench of FreeCAD with 3D object manipulation.
With this file you will be able to print Hergo Rack pegs with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Hergo Rack pegs.
