Steampunk Fixie the Fox Stackable Toy by Rumi-Rumi

Meet the newest character in the Rumi Blocks series — the Steampunk Fixie, ready to tackle any repairs in your imaginative world!

What’s included in the set:
– A fox figure wearing a green work jumpsuit, white shirt, and a belt
– A purple cap with attached goggles
– A wrench — perfect for block-building adventures
– A soldering iron for more complex jobs
– A flexible tail

All parts are modular and fully compatible with other Rumi Blocks sets. The arms are poseable, and accessories can be swapped. Perfect for play, collecting, and hassle-free 3D printing with no s needed.

Steampunk Fixie is compatible with other Rumi Blocks sets: the Christmas Stackable Fidget Toys (the hanging hooks at the top of Christmas blocks may not work with certain fidget blocks, but at the bottom it works).

This fox is designed with modular parts and an assembly-friendly layout. All pieces are detachable: some snap together securely, while others may need a drop of glue for extra hold.

The ZIP file contains STL and 3MF files, including prepared files for AMS color printing, single-color printing, and a 3MF file with all the parts for printing the colorful Fox in a disassembled state for assembly.

The model is for private use only. Reselling, sharing, or distributing the files is not allowed.
If you’re interested in selling prints of my models, a commercial license is available through a Patreon or Boosty subscription.

Technical Note

After printing you’ll need to gently rotate each arm with a bit of pressure. Just make sure to wait until the model has cooled down a bit. You’ll likely hear a soft cracking sound—it’s nothing to worry about! This is a small ledge breaking off, which helped the arms print properly. This ledge also provides slight resistance when rotating the arms, making them more stable, which is a bonus.
