Note on the BOM Iist the cost and the pack cost. There is a difference of $50.00. Some items are sold in packs that leave you with left-over parts if you are just building one printer, but if you are building multiples, those left-over are parts you don't need to buy on later ones.Most of the part list on Amazon can be found on [spam link removed] and are cheaper but have longer ship times.
