Slider for Ottosson Interactive Dog Multipuzzle

Slider replacements used in the Nina Ottosson by Outward Hound Interactive Dog Game Multipuzzle.https://outwardhound.com/multipuzzle-dog-game.html We have the multipuzzle and the dog has ripped out and broken several of the sliders. I'm not sure if the sliders sold on the website are universal between the games, and even if they are, they are sold out all the time. My attempt at replacing the broken sliders. I only have the multipuzzle, not sure if they are inter-changeable with the other puzzles. This is my first ever CAD model built myself, please feel free to suggest improvements. Probably a better way to do supports, but it works. I made an .stl that was filled, and an .stl closer to the original if you need the extra space inside for whatever reason.
