PistenBully modded parts

The scale on these transmissions is enormous, so I'll tackle them later when I have more time. For now, I've simplified them in Simplify3D by scaling them down to a mere .1%. This modification has significantly accelerated the process. Reducing transmission modifications for single belt efficiency has been a game-changer - it's made a substantial difference in speed. The trans braces are positioned above the pulley and contribute to stiffening up the transmission sides, giving me more control over the entire assembly. On the Part 107-side modded model, I've strengthened the front side of the body, but this will require mirroring to achieve symmetry on both sides. To ensure that the transmission belts track straight, I've inserted 5mm spacers between the pulley and bearings - you can use whichever thickness works best for your setup; I opted for 1.2mm spacers.
