This is an outdoor bait station designed to hold 9 1"x1"x1.5" bait blocks with a hole in the center. These are commonly found on Amazon and home stores, at least in the US.

It's sized for small rodents with the openings being about 2". It wouldn't be too hard to scale it up or down with the included Fusion 360 file. I haven't tested scaling in a slicer but that might work as well.

The threaded rods, washers and nuts are #8 imperial because that's what Home Depot had and I wanted to use something I could readily source. Anything of similar size should work fine.

The bolts and nuts for holding the lid are regular 3mm. I used some thumbscrew designs I found here or on Thingiverse. There are dozens to choose from. They're not needed, but I didn't want to bring hex wrenches to open these up and re-bait them.

No special requirements for printing. I used PLA. No supports are needed. Depending on your bridging the slots for the #8 nuts to secure the threaded rods might droop a bit and make insertion difficult.

I guestimate the cost to make is about $3-5. A base and lid take about 5 hours to print on the Bambu Lab X1C with normal settings. Takes less than an hour to assemble, easy to re-bait. The goal was to make something that could be made low-cost, low-hassle and easily replaced if destroyed be either wildlife or elements.
