Little Rocket Transformer Bin: Puzzle Game Mechanical Maze | Pen Holder Storage (Two interchangeable inner barrels)

Update [Added outer barrel vertical placement method] 2026.7.6

Based on friends' feedback, printing diagonally might easily lead to spaghetti issues, so I added an outer barrel for vertical printing. The diagonal print is also kept, and at the bottom, I added a ring of support based on the original diagonal one ~ (I've tested both vertical and diagonal printing for the outer barrel, and I personally prefer diagonal printing because the stars are easier to install) Everyone can choose the placement method according to their machine~~~

First, a reminder to everyone: check if supports are enabled, and try to clean the build plate or apply glue first ~~ Installing the small stars requires some effort because I didn't want to use glue, so the tolerance is set quite small this time ~

This mini rocket set offers two interchangeable inner containers—toy/pen holder, free to switch ~
