Inspired by Moga https://www.thingiverse.com/thing:1991100, I made a customisable initiative tower for my DnD games.
To make it very stable, I added space to put 1cent coins in the base. Mine has 100grams of coin, but 50 should be tons. You can customise this to suit any coins. I put a few drops of superglue around the top coins to keep them locked in place and add to the strength.
Also, it has numbers in the body to indicate the initiative roll. After you have the order worked out the order, you can bunch the pegs together neatly.
It would look amazing with two colors printed.
This is intended to be used with my other DnD accessories.
