DIY FLOATING CENTRE CAPS for $25! (Self-Levelling Wheel Badges)

New and improved version 2.0 available now on my site:

While my $2900 525i isn't quite a Rolls-Royce, I decided to give it a little Goodwood flair by adding some self-levelling wheel centre caps. At about $150 a set though, I was never going to buy them...

In this video, I'm using my new Bambu Lab X1-C 3D printer, along with a couple generic parts, to make a set of floating centre caps using the wheel badges I already have on the car (for about 1/6 the price!)

Download my 3D printable design files here for V1.0:

If you're interested in having me make you a set for your BMW, head to the About section on my channel page and get in touch via email.

Parts required:
M8 bolts, anything over 25mm should work fine
Washers where needed to get spacing correct
22mm skateboard wheel bearings, 7mm thick, 8mm centre diameter
M8 nylon lock nuts
Electrical / teflon tape to wind around section of bolt thread that contacts the inner shell of the bearing, this may be required to get a really snug and precise fit

Note: if you have an open-frame 3D printer (no enclosure) I recommend PETG filament instead of ABS

MY MAN! I have a 3d printer and was just thinking of making these and found your video. Legend! and you've also uploaded the file to thingverse! Not all hero's wear capes!

[mattarnold]

very cool, my first thought was that if you also combined a spring you could damp the inertia of the weights inside and prevent the rolling even more... Just a thought

Well done, man. Great project, great results, and great video production. Good stuff!!!

[Matush]

Def gonna try this on my Saab. No one really sells them and I want them to be good quality.

[ppanczel]

Great video! I was looking for a simple but great solution. Thanks!

Hello, maybe its possible to get 56mm version ? I could downsize it in cura, but then there would be problems with bearing and weights and i still dont have 3d modeling knowledge to downsize only outer edge

Bro would be unstoppable on pimp my ride

[TheJacobs]

Hey man! Great idea great video! Any chance you can post a clear picture of the bolts and sleeves you used?

[Sha_doW_RL]

Do the Caps still work properly without any issue after 8 months?

[mattm]

Great information. I plan on making my own since they don't any larger 3 3/8 inches that I can find and those are $250 each. I want to make custom ones that are somewhere between 5 and 7 inches if possible

Hello man, I just printed the 4, but I can't assemble them well, wouldn't you have a video of how to assemble the screws?

[serdarcam]

you should makes weights held by physical holder instead of gluing it high g forces could easily weaken the glue but overall pretty cool build

How much would you charge me to do mine? I have a 2004 mustang gt and it’s decked out. I’d really love to have some but I don’t know how to create them with 3d printing.

[randygarza]

Nice! Thanks for sharing the project! Any chance you have the bearing part numbers?

[ImanRahmat]

Awesome, wanna trying your model, thanks dude, auto subscribe

[daydaydayday]

Hey, are you making for other people and other vehicles? If so, I have some for my truck.

[DeVeLoPeR]

Hi. Love your work. Do you have by any chance original file(from CAD)? I was trying to make set of those and I run into few issues. Slot for bolt head is bigger so bolt is spinning. And slot for bearing was smaller so grinding was necessary.

Hi Stez, GREAT video. Any chance you could make a set of 4 of these for my 2018 Tesla Model 3. I know it would cost more than $25.00.
