Fat Dragon Games' Dragonlock Miniatures are specifically designed to be the easiest-to-print minis you can buy for 3Dprinting.
These miniatures are optimized for FDM-type 3Dprinters, and do not require the user to do anything special like adding slicer-supports to print them, as the sculpts are designed to self-support or in some cases have pre-designed supports built in. All of this means you can print highly detailed miniatures easily without having the hassles often associated with printing miniatures at home.
Best of all, the miniatures in the photos you see are all printed on a $220 USD 3Dprinter (Creality Ender 3), and a standard 28mm miniature only costs around $0.06 USD to $0.08 USD in plastic to print.
