M4C Shield holes don't line up with IM headband

[forksand]

The holes in the M4C face shields don't identically line up with the pegs in the injection molded version.

TEXLON Injection Molded Prusa Style Band:

Since the peg doesn’t have a radius on the both sides it doesn’t let the inner two slots sit in the
right position

Which causes the outer slot to not reach the peg.

So I widened the outer slot (a bit too much) to get it to fit. Below are two shields stacked on top
of each other to show the original slot and the one I modified.

we fixed this issue with this file: https://github.com/Charlotte-MEDI/Faceshields/blob/master/injection%20mold/Clear%20PETG%20Cut%20file%20(2x3).svg

If you're laser cutting the PETG which it looks like you are, it should be pretty easy to just load up that file and cut.

Ok, but we have some thousands of shields which may not match.

Sofia says she was able to get it to work with the 0.010", but not with 0.020", 0.030", or 0.040".

@Hardikclt Do you know which file made the SVG? I'd like to compare a single DXF with our files and Prusa's. Thx!

I think it was done in corel draw but I'm not 100% sure. Any vector drawing program should be able to open it. If not let me know and I can get you a different file format.

Here's a direct comparison. The square hole on the left side extend 3.3mm wider than our most recent designs. The black lines are current shields; yellow is the MEDI design
