9/14/19 Please see attached reinforced part. I test the stock part in PLA,PETG and PLA Plus and broke all of them in the same spot. I beefed up the arm and reprinted in PLA Plus with no issues.
I broke the stock steering spindle on my 1/12 ECX Barrage and I knew my local hobby shops would not have this part in stock. I started to design it myself but found the exact part finally thanks to TiagoSeverino. ECX shares parts with Redcat, HSP, RGT, FTX and found out Ninco. I made the bearing holes slightly bigger along with the screw sleeve holes.

I am trying this out in PLA, PLA Plus, and PETG.
