Development Notes

It took me 12 hours to prototype and develop the 3D model for this project. The design is optimized for simplicity and efficiency.

If you’d like a version of the STL files without the “Made by Tumba” watermark, consider boosting the model. I'll send you a watermark-free version of the STL as a thank-you!
