Underdesk tissue box side mount

2026/01/10 Version 2 update:
Make the part without hook a bit longer so it's symmetrical with the other part, improving aesthetic as well as making sure it's long enough that the tissue box doesn't slip out.

=====

After using my other under-desk tissue box mount for a while, I realized it's not a good idea to use it upside down because the weight of the remaining tissues will make it much harder to pull a tissue out.
This design address that by hanging the tissue box on its side, making it as easy to pull tissue out as in its upright position.

Changes:
- Moved double sided tape position to the side
- Oval opening on both ends so you can mount tissue box front or back

Print setting:
No support needed. Use brim for "part with hook" if you're not confident, but mine printed just fine without it.
