Spray can straw holder
thingiverse
I chanced upon this https://www.thingiverse.com/thing:5354341 and was impressed with by the simple design. I have a few WD-40 and other spray cans with straws, tried it and it works! I had some initial difficulty inserting the straw into the hole, it eventually went in. And so I did some design changes in hope of improving the straw insertion. I had the hole for the straw elongated and and along a slant surface with chamfer to guide the straw in easier. I did it for the 360ml (65.5mm) and 250ml (52.5mm) can sizes. It seems better to me, hope others feel the same.
