hobby engine crane roller
thingiverse
I'm modifying a hobby engine crane to use Bruder excavator tracks as part of the conversion process. I'll be uploading a front idler as well. It takes 1 1/2 sets of Bruder excavator tracks (3 tracks) for this crane, and it was printed in PETG with support. The crane itself can be obtained through Amazon for $130 shipped.
