Support-free D20 Handbag with modular storage inserts

A fully wearable, 3D printable D20 handbag that actually opens like a real bag. This is our Modular D20 Purse, designed for FDM printing, built around a secure magnetic closure, and sized to comfortably fit large phones (even with a case and pop socket) in a dedicated central phone slot.  Measures 8.5" by 8" by 9.5" tall (phone slot 6.7" by 0.7" by 3.5") The top five triangle panels open along the “lid” section of the D20 and snap closed with embedded magnets so the bag stays secure while you’re out adventuring. Inside, you can choose between included organizer inserts (divided or open concept) to keep your items tidy, with more modular insert variations planned for future updates. This model was originally released as part of our Curations By Kira Patreon pack. What’s includedYou receive the following FDM-ready files: D20 Handbag outer shell pieces with built-in central phone slot Dragon emblem and all number varieties3D printable snap-on hingesTop triangle panels with customizable clasp optionsInterior organizer inserts Divided and open concept setsFull-color .3MF project files (Multi-material) ** Note that for multicolor printing, supports will be neccessary under the numbers due to differences between monocolor and multicolour printing pathways Includes Bambu Studio and generic slicer formatsPre-assigned colour regions for multi material printing Hardware requiredTo complete the physical bag you will need: 4 x 25 mm O rings (attached to the base and clasp)Optional - 7 x 25 mm O rings (or short chain equivalent) to connect rear O ring fasteners. Not needed if using a long chain and doubling it through the fasteners as per listing photos.10 x 6x2 mm round magnetsShoulder strap: Use a purchased strap, or 3D print a chainPrintable chain option (works well scaled up): Use the “Easy Chain” model from Printables and scale as needed. We had good success with 150 links scaled to 145%, though you may want to remove a few links to fit your preferred length. Printing notes:This model is designed for FDM printing with no supports necessary.  Note: No supports were used on anything for the prints in the photos. If you wanted you could use some selected supports for the finger cut outs of the phone holder just to clean up the bridging but its not necessary. Same is true for some of the numbers closest to the build plate on the core d20 model.
