  Update the following line to change which kind of collar is being rendered.
  Available model values: 
    CIR (circle) 
    SQR (square)
    OCT (octagon),
    OCTR (octagon with round notches, seimitsu octo-like)
    OCTN (octagon with deep corners, nobi pro-like)
    SQRN (square with cardinal notches, nobi standard-like)
  Available collar values:
    SHORT (standard short or "chopped" collar)
    FULL (standard full collar)
    STEPPED (stepped collar, like Bandit F3)
    FLAT (flat collar, like alphas)
    ISLAND (unique, almost-full collar. only beveled part of top protrudes when using AFS case)
  For different throw types, change number in brackets (throw_types[x]):
    0 ("S": Emulates full throw of standard sanjuks v6 circle gate)
    1 ("SQ": Reduces throw for SQR model, corners will have same throw as "S" but cardinals are short)
    2 ("SN": Similar to "SQ", but slightly larger. Tuned for OCTN model)

  NOTE: adjusts fit and dimensions of collar to retain same throw as standard 9mm shaft.
  if you want to increase/decrease throw, modify or add values in throw_types
