Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5437961.

The beholder was so much smaller in the first two editions with a diameter range of 4-6 feet. They only have Keratinous plates in AD&D with no mention of them in Basic D&D and none in 2nd Ed AD&D either.

I have included two sizes with one matching the size given in the Monster manual and one matching the size given in 3rd Ed (equivalent to 8ft diameter).
