This is a little base I drew up to securely hold the little pink eyelash extension glue cups commonly available on Amazon and other places. At this writing (June 2025) , you can pick up 200 of these little critters for around 7 bucks in the US.

They can be found by searching for "Flower Shape Glue Cup Eyelash Extension Glue Holder Lash Glue Tray" I printed these on my Bambu A-1 Mini and it took about 20 minutes total at .2mm layer height. If you want to keep them from sliding you can add some of those stick on rubber feet to the bottom
