Edit 23-July-2024:
I know the original version of this design had some issues. I made some updates and put them over on printables a while back. I just put the newer versions on here, hopefully it works better for everyone.

Here's round 3 of the dice storage collection!
This hammer was designed to hold a set of 7 dice (d4, d6, d8, 2d10, d12, and d20). The dice are stored in a tray that screws into the handle. When you are ready to roll you can unscrew the hilt and slide out the dice. There is also some extra storage space located behind the hammer face. This face can screw off to reveal a small cavity.

The front face of the hammer was designed for multimaterial use. The main body of the face has two patterns located in it, a braid around the perimeter and the diamond pattern in the center. In order to print with these patterns you need to split the STL into parts in the slicer. Otherwise you will not see the separate bodies.

Assembly Instructions:
This hammer was built in two main sections: the handle and the head. The handle is comprised of 3 parts. First, the pommel and dice holder files were made to press fit into one another. Then the pommel can screw directly into the handle part.
The head of the hammer is built out of 8 parts. The head connector sits right on top of the handle. Then the spike head and hammer head connection pieces can slide into the hammer connection piece to lock in around the handle. There are four head screws used to lock the pieces together. Finally, the hammer head face part can screw directly into the hammer head connector.
I chose to add some paracord into the groove on the handle for some extra flair. The ends of the paracord can tuck into either end of the handle to remain hidden.
