I couldn't find replacement treads for the NERF Terrascout and I didn't want to deal with printing TPU treads, so I found other projects on Thingiverse to remix. This is still very much a work in progress.
I remixed the track wheel from Staind's RC Tank to match the existing track wheel dimensions on the NERF Terrascout and scaled Oger's Tank Treads to 89.87% to fit the dimensions of the remixed track wheel.
The remixed track wheel fits nicely, but it's not very pretty. A small support is needed on the flat side, but that is all.
You'll need to print 56 treads per side, so 112 treads total. They are connected using M3-0.5 Thread Size, 35 mm Length Steel Pan Head Machine Screws.
