Clear plastic comes from a 1.5L Smart Water bottle from wal-mart.
Treasure is from multiple casts of the Wiz Kids treasure sculpts.
Cut the Smart water bottle to 7 inches. Best using a table saw with a sled and stop block to ensure accuracy and square edge.
Took the sticker off with Goo Gone, but that left a fogging of the plastic. Used some Crest toothpaste on the area, and buffed it with my finger then washed. Took the fogging right out.
The tower was printed on the Voron in ABS plastic.
Valkyrie statue was printed on the Anycubic Photon.
Stairs require supports and a raft. Don't try it without.
During post the ABS print was vapor smoothed prior to priming and painting.
Fusion 360, netfabb, meshmixer, meshlab. A little of all of them.
