flow frame lower plug (ebay)

I found the plugs from Zukibeast did not fit, so i have completely re-designed this version.

This version is slightly tapered to ensure a snug fit, and is slightly larger in diameter.
It fits eBay flow frames nicely.

I have made them brightly coloured so they don't get lost if they were to fall in the grass.

Approx 5 mins each to print on a k1. (3-ish grams).
