So some back of the envelope calculations here...correct me if I misstep: They average 5.70 per product. Assumption - 1 product per hour. Assumption - 20hrs/d

So some back of the envelope calculations here...correct me if I misstep: They average 5.70 per product. Assumption - 1 product per hour. Assumption - 20hrs/day (leaving time for adding more plastic and down time) This totals about $114/day and at 7 days a week this would take approx. 16 days to pay for the box itself. Now include expense of filament (again, approx $20 per day for 20 pieces or so, this is a guess and highly depending on the product and I am assuming they took that into account) for a total of about 20 days of constant 20hr/day operation to pay for just the materials and printer. Now include the costs of creating a queuing system for procrastinators who don't pick up their stuff right away. And technician time to manage errors, refills, maintenance, etc. If you can get 250 people to buy a product this sounds like a decent idea. Now just make sure neat things can be printed and you are a winner. I may have to try this.
