Lack plexiglas window holder

I've made these simple window holder as I didn't want to cut the plexiglas window without the proper tools. Now I can use a 50x50 4mm window for my enclosure. With 4 of these the windows slides perfectly in and fit's really well.

Be aware to print at 100µm as the window can't slide in smoothly with a lower resolution.
I've designed them to fit a 4mm thick window so if you need them a smaller or bigger one just fire up openscad :)
