Helmet harness

I picked up an automatic welding helmet (Speedglas) whose harness was eaten by a dog a few years ago.

I remade the whole harness: soft parts in PETG then bent with an iron in a sheet of parchment paper, rigid parts in PLA. After 3 prototypes and dozens of hours of design the whole thing fits properly.

Ready to weld !!!!

I provide 3 variants of the side joining piece:

1 - Support with Speedglas mounting to clip on the strips

2 - Bracket without mounting to clip onto the strips

3 - Support without mounting to be riveted on the strips (it is easier to mount and requires less preparation of the hole in the strips to avoid tearing the clips, but not removable)

The assembly of the case is done with 4 countersunk head screws 4 mm x10mm

The handle is fixed with a screw 3mmx12mm

(I shortened some screws to have the right size)

PETG straps prints 100% infill crossed lines

Prints of the housing, gear, handle and connecting parts PLA in 50% infill with 4 contour lines

Printing the side part with Speedglass mounting, requires a very light substrate (10-15% infill) so that it can be destroyed with pliers as it is embedded in the part.

I printed the bottom of the case vertically and the cover flat with a support on the inside
