I designed this modular replacement post as a durable, long-lasting solution for worn-out cat tree columns. After getting tired of repeatedly replacing damaged posts, I created a customizable alternative that’s easy to assemble and adapt.

The post consists of two or more screw-together segments. Each segment is 120 mm tall, and additional middle sections can be added to achieve the desired height.

Each segment includes a built-in slot for an M8 nut, allowing secure and stable connections. The maximum supported screw length is 50 mm.

For a personalized finish, the post can be wrapped in fabric, covered with rope, or left as-is, depending on your preference and your cat’s needs.

Instructions:

• 2 walls

• 15% infill

• PLA+ or PETG (preferable)

• Add a pause at layer 52 so you can insert M8 nut (13mm) - only for part1 and part2
