Notice slight vibrations or rattles? Most people don’t, but if you are super sensitive and want to prevent rattling in your tubes - there is a solution!
We’ve come up with a kit to help diffuse light AND help dampen any vibration from the lights against the tubes: http://www.flowtoys.com/parts/vibration-kit/
If you’d rather DIY: The best material we’ve found so far is adhesive window-frosting film, with the backing still on.
For flowlights: You can use clear packing tape or clear heatshrink on the high points of the lights (where they could be rattling against the tube) and experiment with the optimal amount to minimize rattling in your staff tube. We hold very tight tolerances for all our parts, but there will always be slight manufacturing variations in every product.
The tubes have a 1/5000th inch variance, which very few custom extruders are willing to hold, but we found one that would. If it's a little thicker, the caps won't fit and if it's a little smaller, the lights, caps and connectors won't fit. It's a slight compromise for a modular system as we can't just glue everything in place, but most people don't notice it after enjoying their staffs a couple of times.
If you find something that worked that you are happy with, please feel free to share!
