masthandle fits for a Gong Foil Mast v1

this masthandle solfes the problem of carrying a foilboard without a handle on the hull. it only fit on a Gong-Galaxy mast v1 (v2 ist much bigger). i printed it with 15% infill. but of course i am not shure if this is strong enough. but the last 20 wingsession it did not break.
