Based on the main pyramid in the Game of Thrones TV series.
No fixed scale though can re-size on request just based on photos. Roughly 65mm x 65mm square at the base x 67.5mm tall from base to the top. Print in colour of choice or buy in white and paint up.
Could be used in the recent GoT pinball or used to go along with your model sets. It is hollowed out to reduce cost but also allow a light to come out of the window. In addition on the inside under the top has been centre marked so allows you to centrally drill out if you want to install a figure on the top or a light / led.
