This is a stand designed for the Pirate Cutlass series of mice, although it may also be suitable for other mouse models. It is designed for printing in PLA using FDM. It includes two versions. One with a ballast base, and one without. The ballast version of the .3mf file includes pauses to allow the insertion of lead pellets or other weights into the pockets in the base. This increases weight and stability, although the unballasted version is also quite stable.
