My recommendation would be to try and use the low-level methods to create procedural geometry instead of MeshDrawer. It’s not as “quick and dirty” as MeshDrawer of course, but if you can manage to get to grips with how it all works, the low-level stuff will give you the most power to do anything you want with your geometry.
If you find the complexity a bit intimidating, perhaps my proposed new geometry samples can help overcome your trepidation 
.
Once you get comfortable with the low-level geometry manipulation, then this post may also be quite useful to you.
