Ecos bottle detergent Saver

In the world of niche items, this is way up there. Costco sells this detergent for washing machines called Ecos which can be seen in the images. It's great, but there always tends to be a load or so left in the bottom that you just can't get out. So I whipped up this little funnel that sorta locks on the donor bottle and can drain from another bottle set on top of it. I'm not sure how well it would work with a full-ish bottle up top, but this was a quick project with onshape and I didn't want to go too in depth into it. It would probably work for other bottle types scaled up and down. I printed this with Sunlu PETG and supports.
