Simple syringe/flux holder.
Fits into 2x2 modules gridfinity plate, and 4 syringes total.
Max syringe dimensions are 20 mm in diameter and 133 mm long (measured from tip to grip) - basically longest syringe i had with longest needle.
There is easy access for cleaning droplets of whatever you are keeping in it .
If you will orient longer wall parallel to your sight you can see what you are holding in it.
I have used this model as outline base and then modified.
