Made this because i hate gleba and don't want to mess with cloning ore via bacteria and i could not find any other blueprints like this, this makes roughly 9-10 bulk inserters per minute once spun up fully (running at 50% asteroid productivity bonus, would propably net more if it was higher), no quality, although if you can afford it, replace some solar panels with uncommon quality. PS: used the "tiny storage tank" mod at the petroleum and heavy oil fuel line as buffer, reconnect thosse if you do not have the mod. If you're looking for a good design, this isn't it. but it works.
