Good DMs know the power of saying "Yes, and ..." rather than saying "No."  But, there can still be a lot of stop-energy when it comes to rolling accessories.  

For example:

1. "You don't need dice, you can just use an app."

2. "You don't need a rolling tray, I've been rolling in a box lid since 1e."

3. "You don't need a dice tower, just roll on a tray."

4. "No one needs a themed dice tower, a plain one works the same."

5. "You don't need to make your own dice tower, you can buy them online."

6. "You don't need to download templates, you can make one from a Pringles can and dried toothpaste."

7. "You don't need a modular tower, no one even knows what that is."

8. "Don't build so many turns, your rolls are going to be too random."

9. "Don't build it 6 levels high yet, your character is only 3rd level."

10. "Don't make one long path, make two that criss-cross."

11. "Everybody quit encouraging him!"

12. "Don't stand on a chair to roll, I'll get you a stepladder!"

13. "Quit changing it so much, I liked it the way you had it!"

14. "Don't hog that tower, we all helped build it!"

Rolling dice has been pure comfort and joy for over 50 years.  It literally never gets old, no matter how old it gets.  And yet, we had to go and ruin the old way of doing it by showing you the new hotness.

Modular Dice Towers are assembled from hexagonal, soda can-sized paper modules that stack.  You drop your dice in the top, then hear glorious bouncing sounds as they follow the path that you designed, until they exit at the bottom level.

Stacking low is easy and gives a satisfying tactile and auditory experience.  Stacking medium grabs attention and makes an impression.  Stacking high can be a group experience that deepens friendships and makes memories.  Stacking very high inspires awe and complements that temporarily veil deep, smoldering jealousy.
