Corner Drill Guide - Imperial with Interchangeable Inserts

What you should know before printing:

• The inserts fit TIGHT. That is intentional, and you may have to play with your horizontal expansion a bit if it's too tight. My X1C nailed the sizing. Your mileage may vary.
• The actual drill holes in the inserts are a bit under-sized so you'll need to run the appropriately sized bit through for a clean fit. This is also intentional.
• When removing the inserts, push from the top of the cylinder to avoid snapping it.
• There is a blank .STEP file of the insert if you want to make another size. Or ask me and I can.

I saw this in the current contest, loved it, and wanted an imperial version. Then I got to thinking about other features I'd like, and it just turned into a re-imagining of Nico's design. All models are my own but heavily influenced. I used a different size, re-designed the sliders and knobs. I made all the numbers and lines recessed and added multi-sized inserts for different bit sizes. 

Get his model if you want a Metric version. It's fantastic, and I have no intention of making a metric version.
