Parametric holder - configurable shape/size/holes

TLDR: See documentation below for how to define holes before customizing I'm new to this, please let me know if you find any bugs or have any feature requests This is a parametric model for creating holders for brushes, clippers, tweezers, scissors, etc. It has many features, many of which can be seen in renders in the photos: Solid or Hollow body Hollow body for an insert into an existing box/mug/etc Solid body for a freestanding holder Oval or Rectangular overall shape Rounded edges for oval An angled slice of one face for a knife-block style design Overall rotation to control direction of slice and default hole alignment (see the second to last render) Chamfers around inserts and around outer edge of holder I didn't like the look of the hole chamfers with the filament I used, but YMMV Configurable through-holes Define top and bottom shape of hole independently and interpolate between the two Used, amongst other things, to create wedge shaped holes like the tweezers/scissors/comb whi
