Glad you have come to the dark side I'm glad you feel that's good for you as those numbers should be ridiculously easy to achieve. It sounds like there is now a lot more competition for the products you are selling hence why maybe you have gone down in the search. Etsy's algorithm is mostly based on newer items so if you renew your listings a lot they will appear higher. You also need to make sure you have your SEO and keywords on point if you want to be on the first page. When listings are old as yours might be then they tend to show lower down the listings. You should share the listings on twitter, facebook and pinterest too using the buttons on the listing so that etsy thinks this is a popular item and ranks it higher. You can PM me if you want to show me more details if you don't want to post them here and i can critique one of the listings for you to see if that helps. This thread has nothing to do with that. Your post has been reported as I see you have asked the same question many times so not sure why you have come to an Etsy thread to ask. Please refrain from posting non relevant posts in this thread or others. Yeah you can sell that on there. At the end of the day if there are specs out there for someone to make something you are still making it yourself at home. So yeah that's fine but if its someones IP and they make a claim then that could cause problems and if enough people do it you could lose your shop. But as for selling 3D printed stuff as long as you are the one personally printing it them yourself at your location.
