Shimano bleed cup for road brakes with M7x0.75 thread

**Note!** If you are looking to bleed Shimano MTB brakes, this is the wrong part as the thread is larger. I would recommend Scourtade's design which has the right sized threads: https://www.thingiverse.com/thing:4631535 Quick remix of the Shimano funnel for road brakes to fix the thread. Prints without supports. bladel shared the F3D file on the original, so it was quick and easy to adjust the thread to match the M7x0.75 thread used on the Shimano hydraulic road levers. Per bladel's original description: _Should fit all M4 brake levers:_ * _Dura Ace ST-R9120 / ST-R9170 Di2_ * _Ultegra ST-R8020 / ST-R8070 Di2_ * _105 ST-R7020 / ST-R7025_ Note: _the one in the photo is an earlier prototype and the final version available here is larger and better._ This will allow you to bleed road brakes without needing the little white plastic adapter used by the cup that comes with the Shimano bleed kit. (MTB brakes and the Shimano bleed kit use a smaller M5x0.8 thread) I've also adjusted the wall angle on the cup because if you follow the Shimano procedure for bleeding and tilt the bars down 45 degrees and then up 45 degrees, there's a good chance the original wider angled walls would dump brake fluid on the floor. Printing notes: Note that you've got the cup which is a larger, simple shape and doesn't need much in the way of accuracy so can be printed fast and coarse - but then you have the thread which needs to be printed fine for any hope of accuracy. I use PrusaSlicer which makes it easy to choose the 0.3mm layer height, and then adjust the threaded area down to a 0.07mm layer height. 0.1mm would be fine as well, (worked in my prototypes) but it's such a small area at that point that it won't increase the print time that much.
