I've checked my chair and it also seems to be about 28mm at the piston, so more or less it should fit most chair pistons.

Did you end up making one with the hinge mount?

Just did a minor fillet update on the hinge that I forgot to reapply. Should make the hinge stronger. Avoiding sharp corners as that's where plastic is weakest. Regrab the files again now if you like, you'll notice the inner hinge area is now a little smoother.

Like the design/name! Have you tried wiring one of the pucks out of phase?

Hi g_code... Great name.by the way. Yeah that's how it's intended to be wired up. A push pull config should double the vibration energy instead of cancelling out if not out of phase

I printed in ABS first but PLA has much better stiffness. I made one yesterday and will wire it up over the weekend to test it. It's looking promising though.

I printed with 7 walls and it's crazy strong and stiff. Energy transfer should be good and the bolt hole area is solid. It fits the next level V3 motion mount perfectly

I wasn't sure if you designed it for push/pull(had to double check the assembled photo), I looked at your profile after commenting and thought "yeah, this guy knows".

I actually recently upgraded to BST-1s, but I check 'sim racing' here to see what's new. I may try this for my desk chair though. Have you thought about making a hinged arm to attach to chair posts/tube frame rigs. I might try to modify this myself, but modifying stl files is a chore(workable though).

I have another variant with an open hinged pole mount too... It's not finished yet but very close. I don't get alot of free time with the kids, so focussing on just wiring this up today and seeing how it compares to the 4 pucks in chassis mode. I can't have too much shaking as the twin babies still need to sleep.

If you're keen to keep up to date on this stuff too... Simhub has a discord channel. I'm on there mostly now since OZNZ moved web hosts and I lost my whole blog threads for last 3 years.

I was wondering how the progress was on the hinged version, since that would be good for those who just want to throw this on their office chairs.

Oh, it was finished a while ago. The size of the hole for the mounting pole is the only thing to change. Any request for the pole mount size?

I guess whatever the common chair piston size is

I've added the office chair mount. The shaft on mine was an impressive 28mm in diameter. I've modelled to this and given 2mm of wiggle room in the clamp.

The hinge and mount are also 8mm. Depending on the orientation you print with, you made need to run a 8mm drill through to make sure it's nice and round. Tolerances are tight as you don't want it to vibrate on the hinge, but rather be solid and pass the vibration through to the seat.

Print one out and let me know how you go... cheers.
