Initial research

• Wiki article including info on tolerances
• Some Links on 3D printed parts
  • https://i.materialise.com/3d-printing-materials/abs/design-guide
  • http://www.printrbottalk.com/forum/viewtopic.php?f=20&t=4912

Some quick conclusions

• Looking to create a transition fit for the two parts of the sensor housing
• Going to start with the i.materialize min wall thickness (1mm) and min clearance (0.3mm in narrative vs design specs table)
• Going to start with a base thickness of 2mm for added structure
• If needed, will increase thicknesses in 0.5mm steps
• Plan to print with my standard settings (may switch to 100% fill)

After taking some initial measurements, going to use 1.5mm wall thicknesses to match dimensions related to the jack.

Board dimensions = 12.8mm x 17.8mm
Total clearance = 0.3mm
Wall thickness = 1.5mm * 2 = 3mm
Total outer dimensions for box around board = 16.1mm x 21.1mm
Total inner dimensions for box around board = 13.1mm x 18.1mm

Clearance for upper half = 1mm

Finished first revision last night. Still to do:

1. consider reducing upper half clearance
2. determine required height to align with tone ring when mounted on pedals
3. document printer/slicer settings (first in this thread)
4. publish cad files
