### 1/5 — Have to pay

*2026-04-24*

Can’t do anything without buying the PRO version. Not even simply viewing the STL

**Developer response:** Hi. The app includes a free demo file so you can test its performance natively. Viewing your own custom STL files requires a PRO license to support ongoing development. It is a professional tool. You can also view your initial model completely free of charge for a certain period of time, plus we offer a 3-day free trial for full access.
