Chalmers in point 2 is not saying to imagine such a world, but that such a world is logically possible. Chalmers gives as an example of a logical impossibility a male vixen since it is contradictory. He states "... a flying telephone is conceptually coherent, if a little out of the ordinary, so a flying telephone is logically possible. Nevertheless, that zombies are logically possible, may be begging the question, that consciousness is non physical.

To illustrate what can be done with the BOSL2 library for openscad this can add 3 "diamonds" to the RIGHT, FWD, and TOP direction of a square, with the RIGHT and FWD diamond's corner touching the square on the side and the TOP diamond sitting atop the square:

cuboid([8,8,2]) align([RIGHT, FWD, TOP]) cuboid([5,5,2], spin=45);

Another option is the BOSL2 library for openscad which has align, attach and anchor operations and many other useful operations and parts.

In the case of sunlight exposure to UVB an equilibrium is reached where the amount vitamin D produced in the skin equals the amount destroyed by UVB. This does not happen if you pop vitamin D pills. I've recently written an app that calculates the time required to obtain adequate vitamin D by lying prone in the sun, with most of your clothes off, and using MED the minimal erythema dose as a guide to safe sun exposure. At the height of summer it is a surprisingly short amount of time that is required to get adequate vitamin D even for people with dark skins.
