I've been working on mostly 3D printed projects recently. this one was fun :)

A friend of mine is working on a Nautilus/steampunk themed Tiki bar, I wanted to work on a mug for him. 3D printing would be fun but the main issue is finding food safe filament. I have some food safe PETG but it only comes in white and then you have a food safe paint issue. But I came up with a plan. Started with a solid cuboid, hollowed it and cut off the top. Resized it so that the inside would just fit a square glass sleeve. Now the drink doesn't touch the plastic. Downloaded some various submarine themed elements, resized them, and merged them with the hollow cuboid. One of those elements is a porthole. And since the glass inner liner holds the liquid and not the 3D print, I was able to leave the porthole open.

Printed it in a metallic gold filament, then gave it a blue green verdigris wash to look like corroded brass. I like it! Put a LED ice cube inside to really light up the porthole.
