I shared a design for a tissue box in this thread:
Here’s the little brother. I was asked to make one for the smaller boxes by a family member and just got around to it, so I thought I would put that one out here too in case anyone can use it. The photo is showing proofgrade maple and walnut (and it probably will need some glue to stabilize the joints).
Here is the design, just right click on this and save as.
