About this 3D model

I always wanted a specific tool holder that didn't require drilling holes into my printer. So I thought, what better way to start learning 3D design then to design my own. So thats what I did. Neatly designed in Tinkercad. https://tinkercad.com/p/acc0b555ff3849bd/397 What you get: (Or at least what it was designed for)  • 2 holes for common hex keys  • 1 hole for X-Acto or other precision knife  • 1 hole for calipers or scissors  • 2 Slots for tweezers  • +1 Awesome
