H-shifter with sequential mode

thingiverse

This is a 3D printable remix from: https://www.youtube.com/watch?v=FBzPXGkioP8 Mine in action: https://youtu.be/ctGb2LulKnQ Build guide PDF in downloads! Previously I was using the H-shifter from the Thingiverse user Noctiluxx and for me it was too fragile and too light no matter what spring I used, therefore I made this. At the time of writing this I have used the shifter for around 5 hours and have no complaints yet and hope that you guys will enjoy it aswell. The shifter has 3 different modes for the detent spring. If you want you can make the shifting really light, medium or heavy. My shiftknobs inner diameter was 14mm but I printed a 3d printed barrel that I threaded m8 and then pressed it into the knob with a vise. then i put in a m8 rod and threaded it into the 15mm square tube which also had a threaded 3d printed insert. (see photo) If your 15mm tube has 1mm walls use the according files: "insert 1mm wall" *The one I'm using has a h pattern made from 1.5mm sheet aluminium. I myself havent tested the 3d printed version, according to my cad simulations it should work perfectly fine. If there are problems please contact me and I will try to resolve them Included are the drilling templates for the 15mm square tube aswell as a template for the h pattern if you want it to be some other materia.
