Fallen AT-AT Hamster House

I already have an STL of the “fallen AT-AT” planter that floats around the web and now want to turn it into a cozy hamster hideout. The brief is simple:

• Close off the top completely; it should look like solid armor once printed.
• Delete the entire floor so the shell can be lifted straight off the cage base for cleaning.
• Carve a smoothly rounded arch entrance under the rear of the body, between the legs, right where the sculpted snow lump currently sits. Make the opening big enough for an adult hamster yet still in scale with the vehicle.

The interior must stay hollow, and wall thickness should remain print-friendly (about 2–3 mm). Ensure the finished model will fit on a standard 256 × 256 mm FDM bed.

Deliverables:
1. Final, watertight STL (and source file if you work in Fusion 360, Blender, or similar) ready for 0.4 mm-nozzle FDM printing.
2. A brief note on recommended layer height, infill, and support strategy so I can reproduce your test print.

No texturing or painting work is needed—just the clean, printable geometry. Looking forward to your tweak so my hamster can move into its very own Imperial wreck!
