Hi Need help!!! Steamerzone (on thingiverse) has instructions for an all metal driveline, I have purchased all the parts recommended but one area that doesn’t seem to work and I need help on is the wheel axle assembly. As recommended, I ordered the following parts: 4x HSP 188015 Wheel axle ( 2 pairs ) and 4x Axial Narrow 12mm Aluminum Hub Hex AX30427. When you assemble these the end of the wheel axles are too long (D-shaped part), so you have 7mm or 8mm of the shaft spare between the c-hub bearing and the aluminium hub hex (see photo). Also the hub hex’s recommended have a sort of reduced diameter at one end so you cant slide them onto the shaft any further than whats shown in the photo. Can anyone help me understand what is missing or wrong as I have followed Steamerzone’s parts list exactly as instructed…someone else must have used these parts as well? how did you resolve this issue?
These are the ones I’m using:

I have another set, that look very similar to what you have.
You can see the difference in the sizes here:
Hi Brandon, Thanks but they are the ones i already have from before. Using those on my setup requires really short wishbones so that the wheels almost touch the chassis. I have now ordered the parts i mentioned but they have a longer end shaft (part at wheel end) as you can see in the photo there is a big space between bearing and hex hub…really confused as to how Steamerzone, bitfrost and all these other people on thingiverse overcome this problem…the instrcutions do not mention anything…
@Peter_Parnell I can’t wait for the next OpenRC car to come out. Hopefully it will be a lot better and have parts we can order. 
i just looked at your dropbox photo…yeah that’s the one the longer one in your photo is excatly the same as mine and its what Steamerzone and Bitfrost recommend in the all metal drivelines on thingiverse. But how the hell are you supposed to accommodate the longer shaft? No one explains :-(…so frustrating…
You can actually print out your own hex adapter. This way you can make a thicker adapter to accommodate the longer axel. It’ll change the handling characteristics of the car some, but it’ll def work!
Many production rc cars use plastic hex’s already. I’d just be sure to print it with heavy infill and thick perimeters.
don’t think that will work…I’m using the recommended hsp wheel axles for thew all metal driveline and they are a d-faced shaft end. 3d printed ones will not work with this shape they will just strip off in a heartbeat…
Ah, never seen anything like that used before. You could drill a hole and use a pin. That’s how std rc cars do it.
