56mm Spindle mount for an Openbuilds OX

I saw @Eclsnowman 's router mount on Youmagine, and was wondering if anyone had made a 56mm spindle mount for an Openbuilds OX Z axis (20X60 Vslot) My stripped a screw on my existing mount and am now looking for a replacement mount. I liked your design @Eclsnowman , but it is for an 80mm spindle. Someone on OB made a 53mm version, but I need a 56mm one. Any help would be greatly appreciated.

Can’t just clean out and tap up one size?

Give me a few critical dimensions, and I can get it modified. What height do you want it? Are there any other constraints, or mounting locations you want integrated?

And that was my buddy Alex who made the 53mm version. I helped him with the mod of my original model.

In a perfect world it would be 110mm in height, fitting a 56mm spindle, and mounted to 20X60 V slot.

This work?



Yes, and man is it nice looking. I am so impressed with that. I feel like a kid on Christmas morning. :slight_smile:

Going to try that, but the mount was not the best to start with.

Try a Helicoil?

Would it be too much to ask to make it 57mm diameter instead of 56? I remeasured with a different set of calipers and it is actually a 57mm spindle.

No problem I can do that give me a little bit.


Files are in the Gdrive folder for the 57mm now.


You are da man! Thank you very much.

Glad to help. I like these quick designs. Keeps my cad skills fresh.

I’m curious: What are the benefits of this one piece design over a set of separate clamps?

More surface area to lock in the spindle and keeps it better restrained when under side forces.

If it was metal I would say two clamps spread apart would be just at strong. But in plastic it helps to spread out the clamping force across a larger area.

That was the missing piece for me! I was reading it on my phone, where “Printed: PLA / PETG” wasn’t legible, let alone “…Openbuild T-Nut”, and I was wondering whether @funinthefalls had a 4-axis setup to cut the open hardware logo nicely, and the hardware to bore that long sleeve out of a solid chunk of AL stock. :blush:

Only have 3 axis setup right now on my OB Sphinx and OX machines, but the Sphinx will be getting a 4th axis soon.

You able to try printing it yet. Were there any interface issues?
