Insert designed to fit tightly inside a standard Monster Energy can, allowing you to turn it into a functional shift-knob shell.
Tested and finely tuned — fits the can securely without tools. Supports multiple drill sizes so you can prepare the center hole as needed.

This is my first model released publicly, and I’ve done everything possible to make it clean and easy to use.
I removed unnecessary supports, improved geometry for a more accurate fit, and now inserting the piece into the can is much easier.

If you're unsure about the thread size, you can print the test piece first to check print quality and confirm that everything fits correctly.
If the middle section rotates or feels loose, add a small amount of glue — although it should hold well even without it.

If you need a different thread size or have some problem , leave a comment and I will try to update the model.
