MacArthut HAT light pipe harness

Harness to hold light pipe over the MacArthur HAT's LEDs I use the Bivar SMFLP series light pipe, available at Digikey The LEDs are too close together for the light pipe diameter I use so there is not enough room for the adapter Bivar provides. There isn't even enough room for a complete circle of plastic around each pipe. LED spacing is around 2.3mm, pipe diameter is 2.2mm. It means that I needed to print this on it's back but even PLA doesn't seem to have problem flexing for it to clip in place securely
