You can see it being made in to a solid bronze version on my YouTube channel here:
i eventually presented this solid bronze casting to "The Creaky Blinder" (off of youtube) for reaching 5k subscribers and for squashing "flat earth" nonsense on the internets. In fact his version (the one in the video has an added "carved" all seeing eye on the reverse - this model doesn't have that - but you can see the general size and shape on the video)
THIS MODEL IS JUST THE PLAIN STANDARD CURVY YOUTUBE PLAY BUTTON :) it's a very nice thing to hold :)
Size when printed in PLA: 84mm x 58mm x 17mm (high) - play button depth approx 6mm
it has a play button triangle in it with 10 degree drafted sides (this is important if you wish to use it for a sand casting pattern like it did). But it would be equally fine as a 3D printed play button in it's own right.
You can just print the front half if you want a simple one to stick to a wall or plaque etc.
It comes with 6mm pins for lining up the two halves
a very easy print, in two halves with pins for best results.
