Overly-Engineered Tissue Box:

The two-piece design makes it easier to screw under the table. You can see the dimensions (in mm) in the drawing pictures.

The dimension of the tissue box is from Puffs tissue (113x122x129 mm in HxWxD). In the holder's inside dimension, relative to the tissue box dimension, I added about 5 mm tolerance in width and depth, and 10 mm in height for easy take out of the tissue box. I haven't tested with another brand of tissue box. You are welcome to comment on the compatibility of different brands of tissue boxes.

Now you can have your tissue box hidden under the table.

To replace the tissue box, simply lift it a little bit and take it out. There is no need to disassemble the holder.

Print with PLA without any support. You can add a brim to be safe on the print adhesion, However, requires more cleanout after print. For me, I am using a “mouse ear” brim in Orca slicer.

You are more than welcome to leave a comment. I would like to know if my design make your desk cleaner!
