Textured cylindrical lampshade (parametric)

A hanging cylindrical lampshade, with generated surface texture (looks woody or rocky, depending on configuration). Fully parametric including size and texture generation.

Designed to work with my [diffuser insert](https://www.thingiverse.com/thing:7201538) but can be used without. A diffuser which fits these lampshades is attached.

The models here are 200mm high and wide with 29mm hole for the light fitting. You probably want to customise to your desired size and aesthetic preferences (in OpenSCAD). However, I might generate other sizes/configurations on request - ask in the comments.

Note that the model requires the excellent [BOSL2](https://github.com/BelfrySCAD/BOSL2) library (so won't currently work with the online Customizer, which doesn't support this).

**Caution: light fittings can get HOT. A 3D-printed accessory may not be suitable or safe for your lighting. Use at your own risk.**
