Techniques

=Introduction= Casters are one of the most widely used parts and come in many shapes and sizes, often with a 4-hole mounting plate.

=Challenges= Mounting the caster securely through all four mounting holes near a tri-joint (which tend to be at the corners of projects, exactly where casters want to be) isn't easily accomplished.

=Approaches= <gallery> Caster-joint.scad.png|Stronger caster joints Caster-joint-suboptimal.scad.png|Weaker caster joints </gallery> One corner configuration secures the caster at two points and centers the vertical frame member on the caster. The other applies significant force, with the possibility of a bending moment on the caster mounting plate.
