Generate unique, ornamental crystal formations with our latest, free, 3D printable design. This customizable design allows you to choose the number of shards, the number of sides each shard has, their length, diameter, tilt and offset. Then you can specify how much randomness to apply to generate unique crystal structures. This design is completely free and shared under a permissive license. Your support is hugely appreciated. Did you know? Some of our designs cannot be found on MyMiniFactory.

As of version 1.2, a 'deterministic' Randomness option is available. We thank robkingva for this suggestion. In 'Non-deterministic' mode (the default mode and how previous versions worked), OpenSCAD will generate completely new formations as you adjust each Customizer option. To preview a new formation, simply press F5. When you are happy, press F6 to render a random crystal with your chosen Customizer settings. You may need to press F6 a few times but, as this design uses a low polygon count, each new render should be quick. In 'Deterministic' mode, all randomness is derived from the Seed value. This means that for any given set of Customizer settings, the same design will be generated. In other words; in 'Deterministic' mode the randomness is predictable. The suggested way to use this mode is to adjust the Seed value until you find a design you like and then use the other Customizer options to fine tune the design. Once you have chosen your design, you can create a Customizer preset in OpenSCAD so that you can recall and re-generate the same design in the future. This design has the following Customizer options: Randomness Randomness - Type of randomness Seed - Seed value Shards NumberofShards - Number of crystal shards ShardSides - Number of sides each crystal shard has ShardLength - Length of each crystal shard ShardDiameter - Diameter of each crystal shard ShardTilt - Amount of tilt applied to each crystal shard ShardOffset - Amount to offset each crystal shard from the center Variation ShardLengthVariancePercentage - Amount of random variance to apply to the length ShardDiameterVariancePercentage - Amount of random variance to apply to the diameter ShardTiltVariancePercentage - Amount of random variance to apply to the tilt ShardOffsetVariancePercentage - Amount of random variance to apply to the offset ShardSpacingVariancePercentage - Amount of random variance to apply to the spacing Hollow HollowShards - Should the shards be hollow? HollowBase - Should the base also be hollow? Only valid if 'HollowShards' is set to 'Yes' HollowShardWallThickness - Wall thickness of hollow shards Base BaseType - Type of base BaseThickness - Thickness of the base Design Considerations Consider printing this in a translucent or glow-in-the dark filament or resin and possibly adding some under-lighting, using something like a NeoPixel Ring. Material This design is perfect for printing in most filaments, but we recommend translucent filaments/resins in particular for this design. As of v1.1, you can generate hollow formations, allowing for improved lighting effects. For example, you could insert LEDs into some of the shards or use our illuminating base to create a desk lamp. See: https://www.myminifactory.com/object/3d-print-arduino-nano-neopixel-ring-base-171564 Versions 1.2 (14 Jun 2021) Added support for deterministic randomness (Randomness and Seed) - Suggested by robkingva 1.1 (1 May 2021) Added support for hollow formations (HollowShards, HollowBase and HollowShardWallThickness) Renamed Customizer options (Crystal* > Shard_*) Fixed spacing variance bug 1.0 (28 Apr 2021) - Initial version Printing Recommended slicer settings: Resolution: 0.1mm - 0.2mm Infill: ~10 - 20% recommended. For solid formations: Supports: Should not be required. Rafts: Not required, unless you experience adhesion issues. For hollow formations: Supports: Should not be required for the outsides of the shards, but some hollow formations may require internal supports. We recommending using buildplate supports. In Cura set 'Support Placement' to 'Touching Buildplate'. Rafts: We recommend printing with an internal brim for the support material. In Cura disable the 'Brim Only on Outside' setting.
