1980s style roll bar/bed cage/whatever you want to call it.

Fits the WPL C24 Toyota Hilux (and presumably also the C24-1).

Will need to be attached in place somehow. (Mine is actually just held in with double-sided tape, but it doesn't stay in very well.) There are two little pins that fit into the holes on either side of the toolbox where the canopy attaches, while the little feet on the rear part just sit on top of the wheel wells. A small dot of glue on each of the four points where it attaches should be enough to hold it in place (although I wouldn't pick up the truck by the roll bar).

Note that having this installed may restrict how far the toolbox lid can open, but it should still open far enough to get the battery in and out. I had planned to also make a double roll bar version, but I couldn't figure out a way to do it that didn't completely block the lid from opening.

The design is based on measurements taken from the C24 and eyeballing what looks good to me. It is not an exact model of any real-life roll bar, but is very loosely based on the one from Marty McFly's truck (obviously with some changes to better fit the C24).

I recommend printing it in the orientation that it's already in in the STL (front facing down). In my experiments, this produces the smoothest and strongest result. You will need to turn on auto-generated support in whatever slicer you use (all my tests were done with Cura on an Anycubic i3 Mega S). Resolution is up to you, but I'd do it as fine as you can, since this model has a lot of curved surfaces. Obviously, black filament will look best. I printed mine at 100% infill, which is probably a good idea, since you need all the strength you can get.
