I did some #3DPrinting and made a few upgrades for my #G601 .
The first is a pair of upper shock mounts (like I did for my #TL01 except using PETG). Since the shocks were originally mounted directly to the (quite large) chassis, it could cause the chassis to crack if a significant bump happened. These parts also help hold the chassis halves together to prevent dust from getting into the gears.
The second upgrade was a set of wheels (aka "rims"), also in PETG. The originals are chrome plated and known to be brittle. I even ended up cracking one just by taking off a tire! Since there are 6 of them, buying the official parts would total of ~30USD. This set (while not as durable) was ~9USD to print and can be made in any color.

2020-10-08: Updated to v2 which is stiffer. Shock mounting brackets for the Tamiya TL-01. My chassis had cracks in all four shock mounting areas, so I created this part to reduce the stress to each point by spreading the load. It also places the shocks more upright and makes adjustments to threaded shocks much easier. Required hardware: 2x M3x10mm or M3x8mm screws (for each bracket) I recommend drilling this part's chassis mounting holes with a 3.2mm or 1/8in drill bit so that the screws pass through the part without threading.

Got some drivung time with the #M05 a while ago and noticed that it was somewhat wobbly on long straightaways. It turns out that there was lots of play in the axles and steering rack. So, 28 0.1mm shims later, those parts are all tightened up!
I should probably 3D print some 0.5mm shims so I don't have to keep so many unprintably thin shims tied up in this car.
While most of the slop has been taken care of, there is still quite a bit coming from the upper suspension arms and other parts. It's a typical #Tamiya problem that haunts may of their older designs. Since I designed similar arms for my #TL01 , I might print out some tighter fitting arms for this car too.
Took the #TL01 out for its first test drive. It's working pretty well.
I started out with a 21T pinion, but I dropped down to a 19T (the smallest) because the motor was getting fairly hot. It was also ~35°C outside and the road was ~45°C so I'm sure that allowed the motor heat to increase a bit more.
I also noticed a bit of negative camber in the front, so I'll have to lengthen my 3D printed parts a little bit. That's what happens when you don't have originals to measure! 😅
