Eriba puck window locker

On my 1974 Eriba puck, this part was broken. So I designed a replacement part.
This was printed in PETG to resist hot temperatures, with an infill of 40 PCTsto be strong enough.
You must print 3 parts:
- part 1 = it's the base, print it once
- part 2 = this must be printed twice, these holds the metal bolt
You may file the part 2 in order to allow it to correctly fit into the part 1.
Add a M6 bolt in the part 1, then assemble the 2x part 2 arround the metal bolt, then glue them and insert them in the part 1. You may have to force in order to insert them, this will guarantee they will not disassemble later.
I printed mine yesterday, and it fits well :)
Freecad file is given, so if you wish to enhance the design or use it for another project, please do so ;)

Edit 29 march 2020 : I just added the washer on the bolt side (mine was destryed with time)
I also added a picture of the whole set of pieces: so you may see how it should be assembled.

Note: one week and it's still w
