Looking to get some parts made.

Anyone have experience with any of the usual suspects (3dhubs, xometry, rapiddirect) or somewhere local?


If it matters, its a small tool, a torx T-140 if it existed officially. About 1"

I’d be surprised if any local shops wanted to really fuck with that. My guess is the onlines give a better price.

I had something much simpler than that made in a local machine shop (bmw wouldn't sell the part I needed, just a full knuckle). I ended up paying something like $80, which I felt was a huge a ripoff. didn't really have time to price shop though

Frankly, any one-off part for under $100 is pretty fair.

I chickened out on getting someone in china to make it. Lots of bids on mfg.com but pretty risky.

Found someone in PA to make it for 10@$30/ea

That's a damned steal. Figure 30 minutes for CAM. An hour for set up. An hour of spindle time / swapping blanks and tools. This sounds like something that should be heat treated so figure an hour for that.

That's almost 4 hours of shop time which should be $600 plus materials. 1045 is pretty cheap so figure $20.

Again, a steal.

Cool, thanks for the confirmation.

These are 4140 with hard chrome plating.

Some bids on MFG.com were <$100. I can only assume those would be full on chineisum.
Some more legitimate bids would have come out to ~$200 after shipping DHL

Yep. A steal, especially with the plating.

What do you need a T-140 tool for anyway?

Rebuilding Bosch ABS pumps from late 80s cars. This is one tool, once I get in this gate I think that I will end up needing another. These things are an engineering marvel.

T140. If it was T40 he could just buy one. I've not seen a Torx driver at retail bigger than T100.

T140 to 24mm

Gets off these buggers


Torx specifications stop at T100, but this tool was made by interpolating the ratios between T80, T90, T100 etc out to my size. 3d Print prototype fit first try.
