Locking clip for common Swedish 2+1 window

This is a vital locking clip for a type of 2+1 pane window that can be split open for cleaning.

The window type is common in Swedish residential buildings, in this case from the early 1990s, but replacement parts are very hard to find. In Swedish the type of window is referred to as "2+1 kopplat glas". 

Window model

The specific window is not marked with a manufacturer nor a model number, so I suggest you do out a quick print in a cheap filament to check the fit. 

Material

Use PETG or similar so they don't turn brittle over time. The prints uses so little filament so there is no need to cheap out using cheaper materials.

Supports

No supports are needed when printing, thanks to slight alterations to the design of the clips.

Durability and age

The ones in the images was printed in PETG on a Prusa Mini and installed about 3 years ago, they are still flexible and working great. In total 20 or so have been installed since then in various houses in our housing area ("BRF") without anyone breaking so far.
