Description
This is an interesting project that I have started but not finished. I see that there is potential to the design, so I am releasing it to the community for the project to be continued to whoever sees interest or potential in it. This idea stemmed from a Proper Printing video where he tried to make a 3D printed gantry for a printer.
I had looked for an aluminum extrusion replacement that could be customizable as well as expandable, while also being lightweight. I developed this printed skeleton gantry to be stacked with 3 x M3 all thread running and connecting them. 3D Prints are very strong in compression, which is what this design takes advantage of.
They would then be capped with either brass standoffs or M3 nylon locking nuts with washers. I have build a gantry of around 2ft that was able to withstand a 300lb load of force applied in tension. This was done with PLA filament for the added rigidity. I currently do not have any way to transmit 90 degrees with this design. M3 threaded inserts can be melted into the sides to create attachment or mounting points.
Hardware needed:
-M3 All Thread (Whatever length needed)
-M3 Locking Nuts (To cap ends)
-M3 Washers (To cap ends)
-M3 Threaded Inserts (As needed for attachment points on sides)
Thanks!
