Voron StealthBurner SB2209 / SB2040 misalignment protector

BTT SB2209 CanBus boards unfortunately have a design flaw that makes it easy to misalign pins in the board to board socket, leading to voltages being delivered to the wrong places.

This can ultimately result in damage to electronics, such as the SB2209 board or neopixel LEDs. I've experienced this issue personally.

From people comments:

Compatible with:

• SB2040, too

Incompatible with:

• LDO Nitehawk (thicker version is needed for protection to work)
• BTT SB2209 USB with 5 row connector (regular BTT SB2209 CAN has 7 rows connector)

This simple attachment prevents SB cover installation with misalignment. Tested on standard Voron StealthBurner.

Replace M3x6 BHCS with M3x8 BHCS.

Printed in ABS with standard Voron printing settings. Sliced with Arachne wall generator on.
