I know this link existst, but sometimes when it’s treatment season those are out of stock, or take forever to arrive. I can print 4 in a few hours, so it can always help to print one at home. Also, I’m not sure, but I think the ecological impact is bigger if it comes through the Aliexpress expedition than through 3D printing using filaments from Vietnam. But the link is valid, and and is way better to order there price-wise than to order it here!
