About this model

Took a crude attempt at fortifying the connector ends, this was the fastest way i could do it. When I have some more time next week I will try to do a better job of it. This will definitely survive the gentle touch of a 3 year old with only a small loss in flexibility. May not be possible to set Land speed - Print speeds records any longer with these changes.
