A lamen I need to do

So I’m looking to work with Planetary Magick: Invoking and Directing the Powers of the Planets. It requires the use of a lamen, something like a badge of authority or something. So I have a small round steel disk with a chain hole that I want to use. Below is the design of the lamen I’ve created for this purpose, as described in the book.

So, I’m stuck on a few issues.

1st, How should I get the design on the disk? Do I just print it, cut it, and glue it?

2nd, The book says each triangle needs to be colored in at certain times. Is that really necessary?

3rd, Should I consecrate it? And if so, what day and planetary hour?
