JST HUB for the filter

Just use :

• 4 JST XH male 2 pins
• 8 x 40 mm cables
• some heat-shrinkable sleeve
• 2 x m3 T-nut (hammered also)
• 2 x m3 screw (lengh 8 to 10/12 mm depending if using cover or not)

Just have to solder cables to jst and secure it with some heat-shrinkable sleeve. Also better to use loctite/superglue to securise JST connectors. Then connect all 4 wires together by pair and securise with some soldering and heat-shrinkable sleeve.

Better to use loctite/superglue to maintain JST connectors into the hub.

ABS preconised or any other material “heat resistant” since that is close to the heater bed, print it the way this is oriented when importing it (aka the bottom on the bed), don't use supports, bridges should print easily.

Update 11/07/23 : added a cover as requested by a user, but not mandatory (i am not using it)
