Pretty self explanatory of what this item is for.
After 14 iterations I think I've finally nailed it.
I used Voron print settings to print this. This one in particular was printed with ABS.
You will need need 2 x M3 HSI
and as for the 4 screws to the extruder, you need 10mm ones instead of the original 8mm.
