Support post for Injora RC bodies

I couldn't find rods, posts, or pillars, whatever you call them, that would support my Injora RC; those from other brands didn't work for me because they either didn't fit or were too short.

With these, you can put any body you want on your 1/10 Injora RC.

It's printed in TPU, as I initially made them in PETG, and all 4 broke on the first fall. In TPU, no matter how many times they fall, they won't break; you can see the elasticity they have in the photo.
For the long rods, posts, or pillars, you will need two metal crossbars because otherwise, they won't have enough strength and will sag to one side. There's no problem with the short ones. You can see it in the photos.
