STL File License
Personal use license: print the design for yourself, as many times as you like. You may not sell prints, or share, resell or redistribute the files.
Commercial license: everything in personal use, plus you may sell physical prints you make yourself. You may not resell, share, upload or redistribute the digital files, in original or modified form.
Files are delivered as a download link that works for 7 days. Because files are digital, sales are final once downloaded; if a file is broken or missing parts, email me and I'll fix it.
