7+1 speed H-Shifter

thingiverse

Since my old H-shifter is not working anymore, I decided to design one. First I made a wood version, out of scrap I found around the house, and came up with this: https://www.youtube.com/watch?v=763-1WVAYfk It's not pretty, but it's working, and the dimensions are right, so it was a good starting point. What do you need for this project: -Fork: https://www.tme.eu/gb/details/gn751-6-12-m6-b/joints/elesa_ganter/gn-751-6-12-m6-b/ but you can also print one, I just had this around, so i used this one. -M6 threaded rod, and M6 nuts, M6 screws -M2 threaded rod and 4 nuts -Microswitches, I used this ones for the designing https://www.amazon.co.uk/Cylewet-25Pcs-Switch-Arduino-CLW1073/dp/B073XH5TL6/ref=sr_1_1?ie=UTF8&qid=1522524917&sr=8-1&keywords=microswitches -Double roller catch, you might need to position the holes for the mounting on the "core" part, and 3mm screws to mount them -Electronic board, I use one from Leo Bodnar: http://www.leobodnar.com/shop/index.php?main_page=product_info&cPath=94&products_id=183&zenid=637d4a8e757a382eedea23c1651af87c -Rubber band to keep it in the center position Later I will add different sized brackets to mount different types of microswitches. I couldn't print it yet, but I will update with pictures to help the assembly. To assemble the shifter, you need to print one of each component, except the brackets and side. From the bracketA you need 4 pieces, from the bracketB _left and _right you need 2-2 pieces, fromt he side you need 2 pieces. UPDATE1: I printed the core.stl part, the fork had a pretty tight fitting, so I widened the inside to allow for some play. You can see a picture of the assembled part. Also, there are some mounting holes on the baseplate now. UPDATE2: I managed to assemble the brackets and the microswitch. It's not easy to assemble it, because of the small nuts and tight spaces. When I will have some time, I will design a better bracket and spacers to make it easier. UPDATE3: Deleted the old brackets. Now the assembly is a bit easier. Repositioned the holes on the core.stl, so it's in the middle of the assembly now. UPDATE4: strategolie made an arduino program, that can be used for this shifter, you can find it on the following link. Thank you for this, I couldn't do it myself! https://github.com/dahunni/Arduino-H-Shifter-Pedals
