Customizable Sanding Stick

I've created this OpenSCAD, where you can customize your sanding stick. Even the needed screws are printable. You only need some sandpaper (sheet or strip) and the 4 printed parts.

I've also added the four sticks I'm using in the first picture, as .stl files.

Customizable Settings
- set the length, height and width (picture 3)
- 3 different end styles: none, round and wedge (picture 4)
- set the angle and a smooth round end for wedge style

Notes:
You can use lower infill, as long as the infill is present in each layer of the screw. Or you can use separate infill settings for each part e.g. 50% for bottom part and screws, 25% for top part. You can easily separate the part in Simplify3D under Mesh -> Separate Connected Surfaces. You can also separate the parts in the customizer.
