My cats are insane for their food. If we don't feed them on time, they get rough with our cat tree. It's fallen on the floor a few times and the top rips off the bottom, breaking it. We've gone through 2 of these trees so I decided to make a sturdier solution.

PREPARATION

• Catit Senses Food Tree (Version 2)
• This screw will ONLY be able to install if you remove the bottom of the cat tree. I do not have any images of a completed one, but it's the bulbous semi-circle, dead center of the bottom green housing. For us, it cracked and started to split off anyways. To remove the bottom I recommend a craft Dremel/Rotary tool to carefully saw off the piece. This is a VERY brittle plastic that is prone to cracking. I was able to use the dremel to remove the chipped pieces left and smooth the edges so it's not going to cut anyone.
• The white base has a plastic overhang with notches in it. Those notches have 2 thin supports built into them. I used some clippers to snip off those 2 thing supports; leaving the larger snags meant for stopping the top when normally installed

PRINT PARAMETERS

• Use an 85% infill, specifically for the bolt. Anything less and the screw will break where the top and the threads meet. I suppose eventually that will too, but it should last a few knocks to the floor!
• The nut doesn't need to be 85% infill, my first run through was 15% and I've only reprinted the bolt. It's still working fine
• You can size this up/down if needed to fit your hole. I made mine to fit the dimensions of the aforementioned prepared hole. I would recommend keeping the dimensions the same though for a feature helpful during installation

INSTALLATION

I recommend grabbing some long needle nose pliers. After you get it mostly screwed down, you can use the two thick snags to “hold” the nut in place while screwing the bolt through. Make it as TIGHT as you can without ripping the bolt's top from it's threads. It's as simple as that!
