Cheap Ass 6x2 Pneumatic Belt Setup. 3D printed Pulley/ Vex Versa Pulley. Files available

wheels
pneumatics

#161

Double the energy consumption for pneumatics has been the rule of thumb for like 2 years now.


#162

So it works. Works pretty well. The vex pulley adapter is just 1cu inch. So probably less than a dollar to print. Now if only I had a motor to test everything.


Looking for STL files for 6x2 hubs pulley
#163

I’ve used m4 bolts and I can’t find any m4 nuts that sit in the vex pulley nicely… I hate using imperial parts but it looks like the way to go!


#164

Was the pulley 3dprinted?


#165

No, I bought it from these guys,


#166

Seems i am late. The prices rised a lot


#167

what price?


#168

Not 69$ for 4 wheels anymore. I see 18.72€ each


#169

you can still get them cheaper, but there is a difference. The one version that is cheaper can only take 40psi and the slightly pricier can take 70psi.

Hi Guys,

I wonder if these tyres will fit these cheap rims. They may reduce the rolling resistance and increase battery as there is less tyre in contact with the road.


#171

also if the bergmeister tyres fit the cheap rims than these should also fit.

Same ID from what i understand but smaller OD.


#172

Min. Order is 500 pieces


#173

Let’s do an group buy!:grinning: @Trdolan03
Who is in?


#174

What rim is this going to fit? Has anyone here tested them?


#175

It fits haggy board rims.


#176

I want the 6x2 set of haggy board rims and i have a cheap 6x2 aliexpress tyre that i purchased for testing purposes.

Once I have the haggy board set I can then test if the tyres are interchangeable. If they are that means his 6x2 tyres will fit and the 5" ones will also fit. Just have no idea on the inner tube for the 5" ones.

Just found this option for 6x2 tyres if it is of interest


#178

Not really an update but just wanted to show the assembled 3d printed pulley and the wheels. While option2(versa pulley setup) might be more reliable because the pulley is not 3D printed but option1(3d printed pulley and adapter) is very convenient in terms of assembly and disassembly which is what I am using here. I also have a set of versa setup that I’ll try on this board sometime later.


#179

anyone know the size of the print on these 3d printed pulleys from the OP?? I need to know so I can buy a printer big enough for them.

@Lucajo16
If I remember correctly, they should be a around 100mm in diameter and about 20mm thick. The 6in tires are about 150mm diameter.
