A Print-In-Place dice tower and carrier with a hinged tray that snaps in place to act as a carrier as well. No supports required, print in upright orientation at 0.2mm quality. Requires no infill or support. Internal ramps require no additional support or orientation changes, most printers should easily be able to manage the bridging, at worst first few layers of a ramp may have some sag but it shouldn't impede any dice.
2 Versions, a Tall and a Short version, each with covers/trays also provided for replacement in case of damage.
Raft may be necessary if you have trouble with first layer print quality or elephants foot.
