It’s the simple things, right? Like the above mug, called the Drop Rest, which features a small groove around its body that catches coffee as it inevitably makes its way down the side and onto your nice coffee table, sure to make yet another coffee ring. As long as you’re not dropping half the contents over the side, it should do a decent job a catching it all. Of course, what you’re really doing is trading a relatively easy chore (wiping a table) with a potentially harder one (getting coffee out from that recess). That might be the reason the Drop Rest isn’t available for purchase. But with a good number of you now in possession of a 3D printer, this could make a fun weekend project, no?
