Flexible USB light holder for Wanhao Duplicator i3 Plus

I bought 2 USB lights from ebay (https://www.ebay.com.au/itm/122549548735) and I designed fittings to attach them to my Cocoon Create (Wanhao Di3 Plus).

My first try was a clip in thing but PLA isn't flexible enough to clip round a 5mm tube and hold it tight.

This version is in 2 parts that slide together around the 5mm flexible tube of the light. It then clips into the hole between the vertical and horizontal braces of the i3 Plus.
