Here’s my 3D printed dropout for a full sus bike. If I could weld or braze I could make it a lot smaller.

I’d propose to replace the rib/internal flange that separates the two bearings with a circlip as well. This way you can ream it from one side, otherwise the two bearings are never going to be aligned.
Looks sleek though !

Sorry, no photos handy. But here are a couple of screenshots:
Looking good!
I just have one question / concern.
Is the thickness highlighted in the screenhot below 12.5mm and the plan is to have the UDH hanger bolt & washer sit flush or slightly recessed in the dropout?
If so, just in case you’re not already aware, you will not be able to run a Transmission, aka T-type, aka full-mount SRAM derailleur on the frame.

Can anyone help me out with UDH dropouts and the paragon dummy axle. I bought this because my frame jig did not come with one. When installed it’s spacing my dropouts to 160mm. Do I have this configuration correct, I’ve been scratching my head all morning.
What’s the spacer you’re using on the inside of the dropout? It looks like it’s preventing the axle from seating all the way. Also, did you buy the right dummy axle from Paragon? The Syntace version has a larger diameter shoulder on one side if I remember correctly.
I’m currently using a Wolftooth UDH as my spacer.
That’s the paragon 148 axle and the paragon udh adapter. It looks like it’s not there but there is a reference hole the adapter is sitting in.
is that 160mm accounting for the width of the UDH hanger itself? I can’t remember off the top of my head how thick it is from the frame dropout to the hub shell, but I think its only 4mm.
I’m thinking I figured it out. I measured my bike and I have 12mm from inside of dropout to inside of UDH. That should make it correct.

I believe this dimension is 7mm.
But maybe I’m misunderstanding which dimension you’re thinking of.
I can’t picture how you’re mesuring this.
If building for 148mm spacing, then the dimension from the inside of the left dropout to the inside of the right dropout with no hanger or dummy axle UDH spacer in place should be 155mm. 148mm with the spacer (or a hanger) in place.

Good evening!
Is it possible to have a 3D drawing of this dropout?
I would be very grateful.
That was one of my first UDH designs. It’s very heavy and a bit clunky. So I would suggest trying to design your own. With the information on this forum and the UDH specifications you should be able to design something a lot sleeker. I certainly have.
Let us know how you get on!
Thanks for the reply, but I still need to modify it and adapt it to my frame. Do you have anything simple and lightweight for my frame?
Excuse my laziness, thought I catch up this thread when I’m ready for it.
Now I’m about to ma a frame with udh and the tread is long.
My customer wants to use the tange dropouts with integrated brake mounts.
Do I need a specific dummy axle?
And do I understand it right to braze as far as possible to the outside?
Thanks
