Making tea takes some time and space. This caddy lets you bring what you need to the table, easy chair, or patio, where you can make your brew at your own pace. When you're done, it also gives you a place to put the used teabag, sugar envelopes, and other detritus so they don't make a mess or blow away.
The bottom sports a round anchor that fits snugly into your cup or mug, so you can carry both cup and caddy in one hand.

(1) Print 2 items, the tea caddy itself, and one of the discs to suit your cup or mug (large is 77mm, small is 70 mm). Clean up the prints as desired. Note: I printed mine in ABS then put it in an acetone fume chamber to smooth the surfaces for a clean look.
(2) Glue your selected disc to the bottom of the tea caddy. It's a low-stress joint, so anything will work: ABS cement (if you printed in ABS) or epoxy work nicely.
(3) Stock with tea stuff and enjoy!
