Tork paper towel core rocket

thingiverse

This toy rocket is made to build using a core from a Tork paper towel roll. It's meant for kindergarten kids to paint, cut, and assemble. You will need a core pipe from a Tork paper towel roll, which are common in offices across Germany. You can usually get these cores from the cleaning team, as they discard them with paper waste. The core pipe it was designed for has an internal diameter of 38.5mm and an external diameter of 40.5mm. If your pipe has a different base internal ID, scale the design by a factor that matches 100%*real_IDmm/38.5 to make sure it fits.
