Version 7.8 : mid-term overview !

Want to support this project ?

A closed bêta ?

Before starting, what do you think about organising a closed beta? The idea would be to get a small group of people together to make the box, and target different points that I can’t necessarily solve on my own.

Indeed it would make it possible to :

  1. Check that the box can be mounted on various supports.
  2. Check that the box is “buildable” even by people with limited knowledge of printing or electronics
  3. Validate some ideas (the button plate for example).
  4. Check that the box works correctly over time

The 7.8 moves forward…too slowly!

Back to the gearbox. The 7.8 moves forward.

In this version, the electronics have been revised and improved. The principle remains the same: guide all the cables, and indicate as much as possible the mounting diagram everywhere. The realization is cleaner, more practical.

In particular, we now have a “small bridge” that will hold three of the three green cables that will come from the sensor hall on the right (only one cable is present on the photo). There is also a 3 pin dupont connector (in yellow). This will allow the electronics present in the last part of the chassis to be plugged directly.

But we are already on something quite satisfying as it is. The major default of the 7.7 is fixed : the usb connector is now perfectly accessible:

The frame has been refined to be both stiffer and easier to print. In particular, some supports fell out during printing. The first draft revealed qualities and defects, defects that deserve a second printing. One part (the one behind the lever) has not yet been updated.

A large part of the parts have been further optimised. For example, a paddle on the slider makes it easier to switch from H mode to sequential mode.

I also received the screws M5x25, DIN7991 . This is a standard that ensures that everyone will have the same dimensions. The integration is perfect :

The “button plate” mod

As explained in the video on 7.7, the whole project is articulated around an h/sequential gearbox on which various mods are added, including the “button plate”. I made progress on this one, and in particular on the integration of the electronics which is also largely guided.

On the other hand, I would already like to have your opinion on the inscriptions on the top.

I think we all agree that the on/off markings are missing for the ignition and the starter…

A final version ?

There is the question of the release date. At the moment, apart from the obvious corrections to be made, I think version 7.8 is acceptable. Some parts can still be improved, but a first release is envisageable as is. A closed beta would simply allow me to further optimize some parts, while already having user feedback on the box.

In particular, I made sure that the gearbox chassis can indeed be attached to the simulator, and then the entire mechanical part can be installed inside the gearbox.

I've been passionate about cars since I was a kid! I learned the multiple variations of the Skyline R34 through the Gran Tursimo series, until I discovered GTR2 at the wheel of a keyboard. A few years later, I plunged back into Sim Racing with a G27 which made me enter the DIY world. Always looking for an immersion out of reach in reality, I develop projects that I take care to make accessible to any 3D printer owner!

  1. Hi,

    If there is a closed beta i would interested to participate an contribute. I have an Ender 3, basic electronical and 3d design knowledge and have acces to a lathe. I am also currently designing a 3d printed pedal set with loadcell’s.

  2. Hmm.. j’ai cru laisser un commentaire pour declarer ma volonté de participer dans la phase beta :D. Hate de voir et tester ce projet, super boulot!

  3. Hello from the US!!! Your shifter looks absolutely stunning and would love very much to help you test it out! I have a high end 8020 rig and can help with mounting options as I have an ample supply of extra 8020 extrusion! Please let me know if interested and thanks so much for creating this lovely bit of kit, looking forward to seeing it complete!

  4. Hi From New Zealand 🙂
    I would be interested in helping with the beta also. I have a 3d printer and experience with electrical and mechanical systems. Currently making my own belt tensioner and have made an SFX100 system (altho waiting on funds for motors to finish)
    I also have some basic Arduino programming experience. Looks an awesome bit of kit, and I can’t wait to see the perfected design!

  5. Hi from the UK,
    please could i be in the beta too. I have currently printed your hydrolic brake and clutch pedals, but still waiting for some bits to arrive from China so i am looking forward to using them.
    It would be great to test your clutch with your gearbox too.
    I have a Artillery x1 3d printer a modded motion rig with 8040 extrusion.
    I have built my own steering wheel button box and hand made an aluminium sequential shifter and modded a handbrake to a sim handbrake.
    I have basic understanding of arduino and programmed teensy boards, pro micro and leonardo boards.
    I would love to help you with this project as i have been dreaming of a shifter like this for a long time.

  6. Hi from Brazil…
    I was looking your H Shifter and It’s amazing! Seriously, you r a genius!
    I have no technical knowledge with electronics, but I’m a enthusiast and planning to buy a 3d printing just to make this H-Shifter and the hydraulic pedals (still waiting for you to finish). I have a lot of questions on how to build such a thing for someone with no experience with 3d printing.
    If some how I could help, let me know…

  7. Hi,

    I’ve known about your amazing stuff for a while but had other things on the go. I’ve just come here with the intention of building one but if there was a new version going – I’m up for it! I have 3D printers and a hobby CNC plus computing/electrics experience. Love to be involved.
