  • manufacturer name should be lowercase
  • half_skirt should not be in the name because the Plate class has a dedicated attribute for it:

  • the current convention is that the ending _vb should be _Vb (representing "V-bottom"

isn't size_x 126.64?

size_y=85.98, # from spec
size_z=21.08, # from spec, total height to bottom of well

This is incorrect, this is the well size:

-> the well is a subset of the entire plate, i.e. the Well size_z is 21.08
and the Plate size_z is 21.08 + the "wall"/"frame" above it - that is a bit tricky:

the "wall itself" is 10.11 - 7 .57 = 2.54 but looking more carefully at the technical drawing the wells appear to be protruding slightly above the surface.

So Plate size_z is 21.08 + 2.25 - well_protruding_above_surface

This can be very important for a lot of different scenarios:
e.g. we've been planning an anti-crash feature for a long time which relies on the total height of resources to not move into them
e.g. the pickup_distance_from_the_top distance during arm movement will use the size_z as the reference point

when I compute it from the spec I get

dx = (126.24 - 9 * 11 - 5.56)/2 = 10.84 
dy = (85.98 - 9 * 7 - 5.56)/2 = 8.71

do your values work better?

dz=0, # semi-skirted plate
