D20 Icosahedron MOLD / JIG for Stained Glass Making
Our 3D printed mold makes soldering a D20 much easier by creating perfect angles. Accommodates up to 4” equilateral triangles to create different sized D20s. I’m using a 2” triangle for the completed piece shown. Pattern for 2”, 3” and 4” triangles included(Link to download will be in the box).

Add on precut glass for an additional fee. Perfectly cut waterjet equilateral triangles 2” sides. Leave a note at checkout with glass choice and we’ll send options that are in stock.
Made with PLA filament. **PLEASE NOTE** This mold is made with plastic which WILL MELT with direct contact from your soldering iron. Only use to tack this pieces together, don’t solder seams on the mold. 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.TikTok video about this available here: https://vm.tiktok.com/ZTds6aR3X/?k=1
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. Or use 50/50 solder for your inside seams, 60/40 for your outer seams.
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. Instead tack on the mold and use wedges to solder 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 -2 week before it ships.
