D20 Icosahedron MOLD for Stained Glass Making

Regular price $20.00 $0.00 Unit price per

Our 3D printed mold makes soldering a D20 much easier by creating perfect angles. Accommodates multiple sizes of equilateral triangles to create different sized D20s.

Made with PLA filament. **PLEASE NOTE** This mold is made with plastic which WILL MELT with direct contact from your soldering iron. I have made several of these with my mold (pictured) and you can see where I've dripped on the surface causing slight burns but none effect the usage of the mold so far.

For best results: Cut and grind triangles as perfectly as possible, make sure you solder on a lower temp, use flux sparingly and take patience to prevent burning your mold. You can add an additional layer of foil once its tacked together for large seams. Build your outer seams slowly by putting a base layer down, allow to cool, then create your top layer.

Mold works amazing for tacking the pieces together, but if you want to increase the life of your mold, only use for tacking and solder off the mold. For my D20s I have used the mold to tack AND solder on, and you can see there is minimal burning (mostly holes where I placed the hot corners on the mold for doing the seams. Can be slightly sanded if you do make it uneven. Please be aware of this before purchase. I will not accept refunds or exchanges on this item. 

Color of the mold may vary depending on what filament I have in stock. It takes me 6 hours to print the mold, so I will ship as its done. Depending on interest, there may be a wait of 1  week before it ships. 

If you decide to post your creation on social media we'd love a tag to share with other glass artists, not a requirement but super thankful if you do (@bluehillglassstudio).
