Drill guide

##### A little helper for drilling truly vertical holes with a hand held drill

This is for drilling 6mm holes. Let me know if you need a different version.

You need
* The printed parts, (BearingHolder twice, either Base2 or Base)
* 2 ball bearings 626 ZZ
* 2 M4 x 37mm lens head screws
* 2 low profile M4 nuts
* 2 M4 washers

Best results are achieved if you clamp the drill guide down to the workpiece.
