For tissue boxes in the size of 230 x 115 x 70mm. Do you have a different sized box? Use my step-file to remix it to your needs.

I had one random m4 nut on the underside of my table, that's why there is only one screw hole in the model. But for added rigidness I added a bit of blu-tack in the corners that stick to the table.

I also had to split the model into three separate parts because the printbed of my Prusa Mini was too small.

If there is demand, I could add screw holes in the corners and make a one-piece version for larger printers.

Once assembled, attach some elastic bands to the loops. I sewed mine directly onto the part.

Enjoy! :)
