This Mount arm allows you to move the mount from the cross bar to the leg support. my print came out fine and works great. if I needed to reprint again I would change the module mount hole to 9.75 and sand to fit. I did do the print test with PLA, then ended up using PETG.on the actual print. I printed this laying down, hole opening up. only needs a min. of supports where the shaft goes into the frame mount. set random line changes otherwise you will end up with a weak point. placing the Module where shown in picture has so cleaned up the spider web of cables. I'm working on a remix of this with a locking system for Module hole. I suggest printing the test file first.
