yeah I’m fairly confident 5 stars are the same internally.
I want to widen them because they have the 4 inch lip, allowing for some truly phat rubber.
Thank you all for trying though

Would you be interested in making the cad file if I send you dimensions?

Any chance that TB hub spacer stl is up for grabs?
Hey @kook @MoeStooge you guys stretched 6*2 tires right? Whats the preferrable width on them according to your findings? My hubs have them stretched aprox 10 mm now and i was wondering on your thoughts on this.

How can I get this file? Who made it?
Zach did the one for the MBS hub above.
Note that this requires a wider axel as the bearing positions are moved apart.
Unlike the spacer people use on the trampa wheel. Because of it’s 3 piece design the spacer can push the rim out while keeping the bearing positions the same.
the STL for that I swear was in this thread too but I can’t find it.
Is there not a hole for the valve missing?
Is your version compatible with the 5 Star?
I based mine off rockstar 2 hubs. Not sure about 5 star.

Has anyone designed a spacer for bergs yet? Stretched bergs or clever tyres on them would be pretty dank.

Do you really think clever would stretch that much? Lol they’re pretty thick tires

You might talk about 6", I have experience with 8" clever only.
Clever are the cheapest, thickest, heaviest and hardest tires I’ve ever had. Also the most uncomfortable 
But you can stretch them easily, here on 60mm E-Toxx hubs
compared to MBS T1 tire on Rockstar II hub. Clever and T1 are both 8".
Well…

So the @Pedrodemio model didn’t fit the Sunmate hubs perfectly, so courtesy of @Haughbag a modified file which fits. Might be useful for someone. Needs printing at 101% and using supports.
Haven’t ridden, but the test prints look to fit very well

They do actually, my rims stretch them

Another upgrade, following the design of @SimosMCmuffin I decided to add more offset to my hubs with 6301 bearings.
Also this design has two rings to adapt the diameter for 8 / 9 and 10 inch tyres.
The idea is to use an half hypa hub for the external border, considering that is the weak part in 3d printed hubs.

other then metroboard what other tires can be stretched? looking for something slightly larger for more ground clearance. maybe 170mm or so
using 3ds rims stretched with a cf spacer
thanks
