If you want to see a site that is dedicated to sharing things, including all of his own designed plans then look at Jan Ridders site.

This true gentleman shares everything, and only if you ask for one of his great plans is there any mention of a voluntary donation to help keep his site going. But as I said, it is voluntary, NOT forced upon you.
I know of dozens of sites like this, where people share with no thought of making profits, and everything is kept to donations only or totally free.
I hate seeing people starting up a website, and who then start to sell basic model plans STOLEN from other peoples work, who have usually made them available for free on the net.
I spend many of my freetime hours writing up posts, showing how to make things and also designing engines and tooling, making them free to download or see, for anyone who wants them. My time is worth a lot more than it costs to run a website, and I wouldn't even consider charging anyone for the help I give them.
