Inspired by the Bob-omb in Super Mario Brothers -specifically the 1993 movie version. 

The model is designed to use clockwork legs similar to the ones I got on Amazon: [https://www.amazon.com/dp/B0BSBWCPPJ](https://www.amazon.com/dp/B0BSBWCPPJ)

The crank overlay part should friction fit onto the crank, but may need some CA glue if you want it more permanent or avoid slippage. The Bob-omb body has a small tab on the inside to help hold the body in place on the clockwork engine. The body and engine can removed but it will take some effort and a pick can be useful for removing the engine part. The logo on the feet was crudely sketched on, with extra fine marker pens, but I'm looking at getting some printable stickers to make my model a bit more movie-accurate. 

Finally, you can also use a bit of filament to make the fuse for your bob-omb
