NOTICE: As of Sept 2020 I've closed my Patreon account and all my STL files are now shared for FREE over on my blog. [ Ссылка ]
Currently there are over 50 STL files there and I will keep adding more so keep checking the blog for updates. Or if you subscribe at the top of the blog page you'll be notified when a new free model is uploaded. Paul
