Pup cup caddy

These are printed sleeve covers for 3 oz "pup cups" / "parfait cups" with domed tops used in plant propagation. There is a slot on the side to monitor water level while keeping light out of the root area to avoid algae buildup.

Based on the individual cup I posted previously, this was Tim's idea to make caddys.

Fusion 360 project included, which is a parametric design (you can adjust to arbitrary size, and change other dimensions as well)
