Moza AB9 new old school bent lever with N switch

Another Moza AB9 classic muscle car old school style bent shift lever - with Neutral switch (or use it for whatever you want)
I like to match shift knobs to the cars I use in Assetto Corsa. I use this when driving classic cars that have this style knob
I use the switch for neutral gear as I don't like having to knock down 6 gears to get to neutral if I crash.

I made a longer and shorter version.

I recommend not modifying the settings.
 

The main shifter lever set to 4 walls, 10% gyroid infill (If you shift like the hulk print 100% infill)
Screw coupling set to has 6 walls, 100% infill and .25 XY hole compensation (This setting is important for the thread to be correct). 

Short shaft is set to 6 walls, 100% infill.
Knobs set to 4 walls, 10% gyroid infill. (If doing two color knob use at least 6 walls to help avoid color bleeding)

BOM - Purchased parts:
1- 20mm x 6.5mm x 10.2 micro limit switch (pull off the metal lever if it has one) 

2- 0.4mm x 50mm x 10mm. (wire diameter x spring length x spring diameter) I cut it in half and used both halves to make it stronger. 
10-20pcs/lot 0.4mm Stainless Steel Micro Small Compression spring OD 3mm/4mm/5mm/6mm length 5mm to 50mm - AliExpress 13

3- Switch controller - I have mine wired to a zero delay arcade encoder that I have as a button box. You can also use an Arduino (cheaper but will require you to program it).
 

4- M8x20mm conical screw 

Assembly
1 - Insert the micro switch (with wires already soldered) from bottom of the housing upwards with the little red button pointing to the front of the shifter / pins towards the rear of the lever and red button at the top pf the switch housing. ( I put some hot glue on the soldered pins to help secure them).

2 - From the three printed longer Pins; Insert two micro switch pins to hold the switch in place (you may need to scale the pins (increase or decrease by 0.1mm) depending on the filament you are using.  ( see pic below in step 3)

3 - Place the short lever with U opening pointing upwards. Use the third long printed pin to secure it in place.

4 - Place the spring over the switch shaft square end upwards.
 

5 - Slide the top part of the shaft into the under part of the hole in the lever bracket. 

6 - Place the T handle on the top (square) end. Insert a piece of filament to secure it in place, then snip it so it sits flush.

7 - Place the bottom end of the long shaft into the top of the short shaft (u shape end) and use the printed short pin to secure it. It may be a tight fit. 

8 - Use the square hole in the switch housing for a zip tie to secure the wire into place. (When unscrewing/changing shifters over many times it can loosen the solder of the wires on the micro switch so the tie wrap avoids that stress.) 

9 - Attach the ball knob on top and glue into place if needed.

10 - Screw in the M8x20mm screw in the knob short shaft.

11- Insert the short knob shaft with screw in the screw coupling.

12 - Place the lever on the shaft, use glue if needed.

13 - Screw the shifter on to your AB9. I made it so the lever base sits as close to the screw coupling as possible to add contact area for more strength. As you screw the coupling down, feel for when the pins on the AB9 align with the holes in the short shaft.

14 - Then connect the switch wire to whatever board you are using and configure the setup in game.
Ready to race.

For the ball style shift knob I recommend printing at .08mm layer height for best results if printing in one color. (Multicolor will take too long and produce a ton of waste.
