The original is amazing, but there were two small things I had issues with:
Both parts were uploaded as a single file, so you couldn't print them separately. I have them in two files here, so you can just print one or the other, or re-orient them to print a different way.
Even with the slicing tolerance set to "exclusive", I found the insert to be too difficult to push through. I checked the dimensions, and it looks like in the original the hole is 6.7mm x 5mm, and the insert is 6.09mm x 4.65mm (x 44.87 in length). In this remix I shrunk it a teeny bit, to 6.00mm x 4.58mm (x 44.87 in length). Hopefully that's not enough to impact function, but is enough to make it easier to push through. If not, I included the original as well.
