Sharpie Mini (Designer's Placeholder)

**This is a placeholder object for 3D designers.** It was rough-modelled based on the critical dimensions of a real-world object. It has three intended uses:

1. **A virtual placeholder.** Import the STL into your CAD program and then build around it. This helps you position features like mounting holes, and allows you to visualise the design as a completed whole.
2. **A measurement aid.** Open the STL in [Netfabb Basic](https://www.netfabb.com/products/netfabb-basic) and make virtual measure
