I'm still iterating this thing, but it's getting close to done.

## Printed Parts:
- a sanding block
- a ball-joint
- a half-clamp
- angle gauges.

You'll need to print 2 of everything except the gauges.
## Misc Hardware:
- 2020-style aluminium extrusion. I use OpenBuild's V-Slot 20x40 because that's what I had lying around.
- 5mm screws, about 10mm long qty 6
- 5mm t-slot nuts, qty 6
- 8mm smooth rod, as used in many 3-printers. about 30cm (ie: about a foot), qty 2

## Disposables for sharpening
- you'll need sandpaper of a variety of grits, with an adhesive backing.
