FIRST OF ALL, YOU CAN BUY IT AND RESELL IT WITHOUT ANY COPYRIGHT ISSUE.
SECOUND IMPORTANT THING THAT YOU SHOULD READ THE NAME OF ALL THE FORMATES CLEARLY BECAUSE THERE SOMETHING IMPORTANT TO UNDERSTAND FOR EACH FORMAT ITSELF.
THIRED THING IS THAT YOU CAN USE THIS MODEL EITHER FOR VISUALISING OR 3D PRINTING OR OTHER PURPOSE ALL THE FILES YOU NEED ARE HERE.
NOW TO MODEL IT SELF it's a very detailed 3D model of bitcoin coin made in blender 2.83 and there are 4 files format of it stl, obj, fbx and also the blend file ( the original file).
it's diameter about 2.5 cm in Halot box software.
also there was 2 obj files one of them I didn't apply subdivision surface in it so you can make some adjustment. also in the blend file there was all you need to adjust it as you want, and there was a camera animation turned around the bitcoin.
also the stl files are 2 one of them is normal file size about 55 MB and the other is huge it's more than 354 MB that because I have applied more subdivision surface modifier level to make it more smooth so take that into consideration.
THANKS.
