Hi RinconFabLabMaker!
I can try and have a little look at your Sketchup file.
If there are some objects that does not need to be there and can be removed to reduce size I can remove them for you and save the file so you at least can open it and decide on further reductions of polygons and/or textures.
Upload the file via Firefox Send or similar service, then PM me the link and I’ll take a look.
