Description
TRX4M shock tower front and rear. Designed to fit on the stock chassis/frame rails, but may work on aftermarket, LCG, etc. I designed this to dial in the suspension on my TRX4M with Injora IR60 body: I was having clearance issues with the servo in front, and limited travel due to the  rear links hitting the bottom of the stock shock mount. This is now a two-piece front shock mount (as opposed to the stock 1 piece), and a 1 piece rear shock mount which also doubles as a platform to mount batteries, ESC, etc, and this frees up a lot of space on the crawler. The top shock mount now sits about 3mm further back so it is not so straight up and down. The same goes for the rear, it sits about 3mm further forward to introduce angle into the shock. It uses the same size mounting hardware as stock, as well as the same holes on the chassis. Profile is for 0.16mm layer height Bambu ASA. I've had success printing the front mounts on their side, as well as on the flat face where the chassis mounting holes are on the bottom. For the rear mount, I recommend printing  on the flat front part of the mount at a 45 degree angle (this is also best for strength). Auto-rotate feature in Bambu Slicer should put these in the correct orientation, but print as you see fit.
Boost MeIdk exactly how boosts work, but I'm just tryna get a discount on the new Bambu printers ;)Boost MeNew to this, but I hear boosts are good? :)License:
