Many things have screw mounts. With this script you can create one that holds your tools and devices snugly.

Instructions

Local

1. Download the latest OpenSCAD Development Snapshot. OpenSCAD is free software.
2. Launch it and open the attached hsw_peg.scad 
3. If you do not see the "Customizer" pane click on Window -> Hide Customizer
4. Enter whatever parameters you want
5. Press F6 or Design -> Render
6. Press F7 or File -> Export -> Export as STL

Web  (Alternative)

If for some reason you can't get it working locally you can use https://ochafik.com/openscad2/ to customize the model using your browser.

As every printer/material combo will slightly vary the print's physical dimensions, you might need to adjust hsw_insert_diameter to get a better fit with your insert.

Note that the peg cap extends above the peg itself, so the distance from the HSW insert to the very tip of the head is peg_heigh + cap_height.

If for whatever reason you are unable to use the customizer, I provided an arbitrary selection of pegs. Left to right the peg heights vary from 5mm to 25mm in 2mm steps. Bottom to top peg diameters vary from 4mm to 9mm in 0.5mm steps.

Let me know if you have any requests.
