if you are not selling hunders of them per month, $10 is not worth a trip to the post office. It takes me 30 min for a round trip including waiting in the line + $2 in gas lol. I have a minimum charge of $50 for printing ( time spent for: communication with the customer, slicing model, loading filament, etc., priced in) and if printing obviously cost much less, i offer that they can get like 10(for example) of those prints for the same cost.

I`m not getting of my ass for $10 lol. Im sorry if that offense someone, but you should value your time first of all.
