About this 3D model

I needed a coaster that fitted my favorate mocca mug...tinkercad is cool, i messed with some parts i found (Tinkercad Printable kits, skull and foot parts) then fiddled somemore on FlashPrint and came up with this.i first made it with the caffeine base but then decided to print one with my logo.Once this was seen by others i got requests for ones with personlised centers so i have also included a plane file for download.70mm cup base and stackable. Enjoiy! :)
