Charge for what? I do have an eBay store where I sell custom designed upgrade modification to a technology festival cat litterbox. The thing can probably blast off to space. Anyway, I sell those items for 9.99-14.99 and I sell my combination pack of all of them for 42.99. Each piece takes 45 minutes to 1.5 hours to manufacture and costs me 0.86 in material costs plus 1.5 hours of electricity. I have another modification on the horizon which is large (4.5 hours to manufacture and $3.35 in material costs) which I plan to sell for $30-45 I havent decided yet. It has been an engineering nightmare to design. These products can be offered at a cheaper price because they're only designed once and dont need constant updates.
As for
FSF Print House we havent decided on pricing there. These items will likely require a lot more design work, far fewer sales, much longer manufacturing times, and much higher material costs...all this to say I think the FSF merch will have to be a little bit higher, but we obviously need to balance the sale price and the "
is it worth it to buy it at this" price, so more to come on that.
As for someone random joe that wanted to use my printer, I would gladly let someone do that if they had the files already designed. I've never had someone ask, so I dont know what the rates would be, but I think 3D print farms operate on a very similar pricing as to CNC machines, which is to say that there is a standard price per unit of material, price per unit of time, and a base offset. So a 3 hour print would probably cost the buyer round $20-$30 depending on material. I would love to hire out my 3D printer to people that already have designs but no printer, I just dont know how to even market that lol.
