My process has shifted a lot since I started. In the beginning, I was strictly downloading ready-made files because designing felt like a massive skill wall I didn’t have time to climb. But I realized that even modifying existing models is a huge step—just learning to split a model into parts for better printing or adding a simple peg hole for assembly teaches you more about tolerances than any tutorial will. For ready-made game assets specifically, I’ve had the best luck with https://www.gambody.com/ because their models are pre-split and pre-supported for FDM and resin, which saved me from the nightmare of figuring out why a dragon’s wing kept failing mid-print.
