Yeti Rambler Colster Tallboy 16oz to Standard 12oz adaptor

This is a spacer for fitting a 12oz can in a 16oz Yeti Colster Rambler. The concept behind this is to reduce thermal conductivity by reducing the contact area of the can and completely fill the gap below the can so heat is not lost to the dead air space. The spacer is intended to be printed with an infill of 12% so that it is mostly a sealed air chamber and I used a rectilinear infill to further reduce the thermal conductivity throughout the spacer.
