Inserts for a hollow book safe to turn it into a dice tower and storage. Will need to be scaled to fit whatever book you use as none of them are the same size. Printed on my Cr-10 S5. Id recommend using a raft on the storage compartment piece since there's such a small footprint touching the bed. the dice tower prints fine without one and no supports are needed. My first time designing anything, so its really basic but functional. I ended up adding a small strip of velcro to the base of the tower and my book to hold it in place since its so light.
*Finally got around to adding the separate storage compartments and some pre cut one.
