These devices are awsome i first seen a version from
The movie Aliens over a decade ago .
My nephew starting a Landscaping Business would greatly benefit from such a device . Allowing him to do more with less effort. I would like to see a line of these sold at Home depot across North America

I am curious about this as well, the key is finding a material that has a low melt point (as in can be printed with) but a high Tg (wont melt when injection molding the lower temp plastic)
