# Glow Lantern Zipper Pulls ## Overview https://youtu.be/-howWqBSjh0 In this project, we’re making 3d printed accessories with glow in the dark powder. We were inspired to design zipper pulls that glow in the dark so you can see them at night. A 3D printed case with built-in threads and a screw cap holds a small bottle charm with glow in the dark powder. ![3d_printing_hero-close-small.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/485/medium640/3d_printing_hero-close-small.jpg?1646670507) You can 3d print them in different colors to match the powdered pigments, so there are lots of options. The powder comes in different colors that are fluorescent under blacklight and charge up when exposed to sunlight. Our 3D printed containers are sized to fit these little bottle charms that we got from our local crafting supply store. ![3d_printing_hero-glow-4-case.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/486/medium640/3d_printing_hero-glow-4-case.jpg?1646670610) ![3d_printing_powder-colors.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/487/medium640/3d_printing_powder-colors.jpg?1646670651) We designed and 3d printed a little funnel to make filling the vials much easier and way less messy. Using a spoon to add small amounts of glow powder at a time avoids spills and overfilling. Once the bottle is filled up, we'll seal it with the cork tops that were included with the set. The bottles just slip right into the canisters and the cap is screwed on top so they’re nicely protected. ![3d_printing_funnel-fill.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/488/medium640/3d_printing_funnel-fill.jpg?1646670804) ![3d_printing_bottle-insert.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/489/medium640/3d_printing_bottle-insert.jpg?1646670912) Lastly we added a split ring to the loop in the screw caps to secure the bottle. We hope this inspires you to 3d print your own wearable accessories and try out some glow in the dark powder! ![3d_printing_hero-wear-small.jpg](https://cdn-learn.adafruit.com/assets/assets/000/109/490/medium640/3d_printing_hero-wear-small.jpg?1646671298) ## Parts ### Part: Glow In The Dark Pigment Powder quantity: 1 Neutral 5 Color Pack Glow In The Dark Pigment Powder - 12g Each [Glow In The Dark Pigment Powder](https://www.amazon.com/gp/product/B01K0YRDOQ) ### Part: Assorted Glass Bottle Charms quantity: 1 Package contains 8 bottle charms [Assorted Glass Bottle Charms](https://www.amazon.com/s?k=Assorted+Glass+Bottle+Charms&crid=13WBRS4DB3ZXE&sprefix=assorted+glass+bottle+charms%2Caps%2C203&ref=nb_sb_noss_2) # Glow Lantern Zipper Pulls ## 3D Printing ## Parts List STL files for 3D printing are oriented to print "as-is" on FDM style machines.
