Im planning on building a whoop and one of those looks pretty nice!
I also have lots this 10mm PVC pipe that come from curtains of a place I rented, I grabbed them before the guy tossed out old ones and about 25 in total with 1.7m's in length.
then designed joins connector so im able to cut to size i wish and assemble to make gates, printing one set in Red filament so it can be used for Strat and Finish line. in total 7 gates are made.
Fits 10mm Diameter pipe I used 45dg angle to make octagon gates, 90dg angle to make square gates as well as T pieces so there able to be head standing upright. then 2 different designs for holding the gates in place feet with wide surface area, plus a 90dg block so it able to hook on to something like door jamb, wall or window.
Feet
If any one like a copy of the STI files i can post them up.
As well i be adding Led Flexible EL Wire Light Rope Strip 12V so it can be used at night.
