I like the design by ChatterComa (https://www.thingiverse.com/thing:867811) but wanted a little bump to get every drop of toothpaste from the tube. I designed this with a bump on one side to squeeze into the toothpaste tube end and get the last little bit of toothpaste out of the tube, rather than fumble with squeezing it at weird angles to get everything out.

Simple print, takes about 45 mins, no supports, I printed in HTPLA+ (Fusion Filaments 870), but any material should work.

UPDATE: 2021.02.15: Added a thicker version in case anyone wants even more pushing power.

I do this for fun and no support is required. However, if you want to donate use my PayPal linked through Thingiverse or use an amazon affiliate link: amzn.to/3c3d5ou
