Customizable Detector Cap Check Source Holder

Customizable version of a check-source holder / detector cap I made for using with our HPGe detectors. Note that no extra tolerances are hard coded in - you should add the necessary amounts for your printer. Don't forget to consider thermal expansion (contraction) of your material if utilizing for an HPGe or similarly chilled detector.

Parameters (mm):
$fn = resolution
cap_height = total depth of cap
inner_diameter
face_thickness
standoff_width = width of ring around the inner perimeter
