I'm still using a generic (non hot-shoe) item I bought in the '70's ... these days I use it in conjunction with a clone Pentax-compatible flash extension lead. Not "perfect", but a lot cheaper than any OEM or "custom" item and perfectly serviceable
I think the poster is taking about the tripod mount type L-bracket. The one that screws into the 1/4"-20 screw socket on the bottom of the camera.
To the OP, essentially, none exist specific to the K-70. There are universal L-brackets but none I've seen specifically designed for the K-70. When I had a K-70, I had deigned one and I think it's still up on my Shapeways store but I never made one in metal. I ended up moving on from the K-70 to a K-3II so I stopped developing my L-bracket design.
