* 2019-04-19 notes for as-built units

Current drawing is for 16mm tubing, which matches the long arm of our C-stands.

The original design include variants for 16, 19, 22, 25, 30, 35mm diameters.

It still has 6mm holes.

* C-stand tube dimensions

1. main vertical: 35 mm or 32 mm
2. leg: 25 mm
3. end bar: 16 mm

* 2024-02-20 updating design for S24

1. duplicated ~/SolidWorks/Kinetic-Fabrics-S19/tubing-clamp/

2. tubing-clamp-cam.SLDPRT
   1. verifying the pivot hole is still 6mm (for M6 screw)

3. tubing-clamp-plate.SLDPRT
   1. suppressing the captive #8 slots, they seem unnecessary
   2. verifying the pivot hole is still 6mm (for M6 screw)
   3. verifying the default tube slot is 16 mm
   4. verifying the main mount holes are 6.35 mm
   5. the smaller mount holes are 4.05 mm
      1. (/ 4.05 25.4) = 0.159 in, which is a body drill for a #8 screw
      2. I stock eyebolts in both #8-32 and 1/4-20 threads, so this matches
         1. McMaster-Carr 9489T112 and 9489T121

4. exporting:
   1. default 16mm slot as tubing-clamp-plate.DXF
   2. alternate 23.5 mm slot as as tubing-clamp-plate-23.5.DXF
      1. not exactly sure what this fits
   3. standard cam as tubing-clamp-cam.DXF
