30. Bell Design

Ready-to-use parametric bell design. It is the extremity piece of a gimbal assembly. The bell piece is composed of several flat parts fixed together.

To get an overview of the possible bell designs that can be generated by bell(), run:

> python bell.py --run_self_test

30.1. Bell Parts and Geometry

The bell is composed out of the following flat parts:

  • bell_face x2
  • bell_side x2
  • bell_base x1
  • bell_internal_buttress x8
  • bell_external_buttress x8 (alternative: bell_external_buttress_face x4 and bell_external_buttress_side x4)

30.3. Bell Parameter Dependency

30.3.1. router_bit_radius

The two parameters leg_smooth_radius and cnc_router_bit_radius are related to the router_bit_radius. The parameter cnc_router_bit_radius guarantees the smallest possible router_bit_radius value. So, we have the relations:

cnc_router_bit_radius < leg_smooth_radius
