Siraya Resin Bottle Adapter

thingiverse

As a teen, I worked in restaurants where we emptied every last drop of ketchup from the old bottles into the new. Photopolymers are more expensive than ketchup so I do the same thing. There are others but this one is sized for 1 kg Siraya Tech bottles. My CAD has a problem, it won't thread beveled cylinders and it won't bevel threaded cylinders. I put one cylinder for threading inside another cylinder for beveling to look pretty. I'm not sure it won't print standing upright without supports but I tilted it and supported it to make sure it would print without problem. I'm pretty sure a crude version would do the job but I printed it at less than 50 μm resolution to look pretty.
