DIP IC Test Clip by Naturaltangent

Parametric DIP IC Test Clip.
This is heavily inspired by https://www.thingiverse.com/thing:1104612. I wanted to make some adjustments to attempt to increase the grip on narrower ICs, so re-approximated it using OpenSCAD. I'm not sure I've improved anything, but it's a starting point.
Print 2 copies to make a single test clip.
You will also require;
Metal pins to act as the clip contacts - I used 'Gold Brass Flat Headpins 50mm x 0.7mm Jewellery Making' from ebay.
A hinge pin. I used 2mm silver steel that I had in my scrap box.
Springs (1 or 2 depending on the length of the test clip). I made my own using 0.8mm 'music wire' and a lathe. You can probably buy springs - the length depends on the size of the IC/clip.
I need to print with 0.1mm layer height to have enough accuracy for the clip pins to clear the holes.
So far, I have only printed the following versions (all other parameters left at default);
STL
ic_pin_count
ic_width
dip_clip_16.stl
16
8
dip_clip_40.stl
40
