Pi ZeroW case with screws and CS mount

<p>Slight remix of bobtidey's excellent design (I love the camera cable slot and the fact its OpenSCAD!)</p><p>I've basically changed it to take m2.5 (id) x 3.5 (od) x 4mm long <a href="https://www.aliexpress.com/item/UXCELL-M2-5-X-4Mm-3-5Mm-Od-Brass-Threaded-Insert-Embedded-Knurled-Thumb-Nut-100Pcs/32776245817.html">knurled inserts</a>, made it slightly taller, removed the screw countersink (as I plan on using <a href="https://www.aliexpress.com/item/304-Stainless-Allen-Bolt-Socket-Cap-Screw-Hex-Head-Allen-Key-DIN912-M2-5-4-5/32789763655.html">allen hex heads</a>) and formatted the code a bit.</p><p>I made the base a bit taller to accommodate the ZeroW and larger HDMI cables. Made the holes through the base M3-sized so that the M2.5 bolts have some wiggle room when trying to line up with the M2.5 knurled inserts (I can never get them in straight!) Also added a chamfer on the supports to add some strength at the base to stop them snapping off if you apply too much lateral force.</p><p>Test prints fit fine with 8mm long M2.5 bolts.</p><p>I plan on making another version with the screw holes that go all the way through to be bolted together without the knurled inserts, and maybe use M3 nuts &amp; bolts (you can widen the Pi holes a bit with a tap or a self-tapping screw) as they're easier to find than M2.5</p><p>Added a new version with a C/CS lens mount (and M12 mount within it) with the camera module inside the case.</p>
