The 3d-models of the cat bed from https://www.reddit.com/r/3Dprinting/comments/xbd2ba/desingned_a_window_bed_for_our_cat_she/ Reddit post.

The models are not perfect since i created this to learn how to use Freecad and to make a cat window bed of course :)

I used a broom handle as part of the frame, and suction cups to hold the bed to the window. I've learned that not all suction cups work as well, so make sure to get some good quality ones or maybe use strong adhesive instead.

The corner parts are glued together. The amount you need to print of a part is specified in the file name.

Print the corner parts standing up and mirror on of the the "corner_front_2x" for the cord.

This cat bed isn't perfect but its still standing to this day! (~1.5 years)
