3D Printed Cable Mount
Just recently (Oct 2017) I chose to replace the wiring loom in my engine bay, the cable that controls the injectors and CAM position sensor had no support, the purpose of this project was to create a support via 3D Printing.
A quick sketch was made of the dimensions that I will require, this is my rather cryptic looking sketch, it makes sense to me however.
These dimensions were then put into a 2D design, I used Solid Works, all of the dimensions are metric.
Next was to make an outline of the finished piece, most of this is guesswork but bearing in mind this won't be effective if it is flexible.
The part was extruded to a thickness of 6mm, maybe I should have gone 8mm but I guess time will tell.
A plane was created so that I could draw the outline for the hook that will hold the cable.
The hook was extruded.
I couple of fillets around the edges to smooth the design a little.
The file was then saved as an STL in order for it to be 3D printed, an STL file composes of many triangles, the wire frame below gives an indication of the amount of triangles required.
The part placed into Cura for it to generate the G-code.
Here is a view that shows all of the print layers, I had to print some support as 3D printers cannot handle over hangs.
The part was printed from polycarbonate to handle the temperatures in an engine bay, the print support was removed to expose the final product.
Luckily my guesstimate dimensions were pretty good and the part served it's purpose.
