Looking for a couple of .stl files

[Oscar at Play]

Recently I have been successfully printing out replacement parts for those brittle plastic bits that break. So far I have done roof vent stays and plastic blind parts as well as custom washers.
Most files seem to be able to be found on thingiverse, but I am struggling to find two that are needed and my CAD skills are non-existent.
Any help, advice or indeed files would be most welcome.

The files needed are:

1) The sliding window catch in the side door. The whole thing is not required, only the lever parts.
2) The white end catch that is secured by two screws on a FIAMMA F45 awning, if you look at the picture the inside (left) triangular catch has snapped off. I need both sides, but I assume that I can just mirror that from one file. Unfortunately this part is not available as a replacement so far as I can tell.

Mmm, it's amazing what you can find on Thingiverse but they both look very specific and I imagine complicated to draw.

Have you tried tinkercad for designing what you need? Remember it doesn't have to look or be identical, it just has to function and be made of the right plastic filament not to break. Making most things on tinkercad is just adding shapes to other shapes and making the either solid or holes!

There are loads of tinkercad videos on YouTube to help and it's free cad software.
