Add On Options
If you’d like to order a printer as well as one of our add ons, please pledge for the printer reward that you prefer (Kit, Assembled, or Pro) and then up your pledge by the cost of the add on you wish to receive. You may order multiple add ons, however please note that it is against KS guidelines to sell quantities higher than 10 of any single item. We do not offer combined shipping, so for example if you want to add two litres of resin you must also add $20 for shipping.
