Magnetic Paddle Module with Dual Clutch, Shifter and Additional Buttons for Sim Racing

Update 01.2024:
I redesigned this a while back to have shorter throw, better overall feel and beefed up mount. As usual all details you can find on my website:

Extended my Magnetic Paddle Shifter design to feature Dual Clutch and additional buttons. Clutch utilizes Hall sensor and magnetic sprint (2 magnets with reverse polarity).
Shifter has short-to-medium throw, added second magnet for additional strength.
Paddles are from my Bentley GT3 Replica design: https://www.thingiverse.com/thing:5503879

The whole assembly is very stable and feels extremely nice. Works well directly with Fanatec Podium hub, can be configured with Arduino as well.

All openings are very tight to assure stable fit, but with my printed they did not require almost any post processing.

Remember to reverse polarity on the bottom clutch magnet - it has to push the paddle away. Also keep in mind hall sensor has polarity - it is possible that you will need to flip all magnets if it does not work.

Parts needed:

1. Neodym Magnets 15x4mm - 14-16x (depending if you want more magnets on shifter for stronger feel)
2. Omron micro switch or clone with straight handle - 4x: https://www.aliexpress.com/item/32273125391
3. M3 Standoffs (o.d. 5mm), 18mm long - 12x: https://www.aliexpress.com/item/1005001711916538
4. M3 Alu washers for slick look, not so needed - 8x: https://www.aliexpress.com/item/32968161596.html
5. M3 countersunk screws for clutch side assembly, I used 16mm ones - 4x
6. M3x50mm countersunk screws - for shifter assembly, they hold together the three standoffs in row - 4x
7. M3x12 round head screws for shifter and clutch paddles, mounting baseplate - 12x
8. M2 screws for switch mounting, at lease 16mm - 8x
9. M3 nuts for holding mount plate
10. M3 brass 3D print inserts, 4.2mm o.d., 6mm length - for paddles/flat base - 12-20x: https://www.aliexpress.com/item/1005003582355741
11. Magnetic Hall Sensor SS49E - 2x: https://www.aliexpress.com/item/1005002287050188

Included are two mounting options - Fanatec hubs/wheels and flat button plate (bottom mounted).

N.B.! - Flat mount was not tested, it is meant for brass inserts as well. I do not see a reason it shouldn't work though...
