It got damaged while I was using it and you can't buy it separately. So I made one based on the original with minor modifications. The holes are not conical, they have a straight guide, there is a smaller radius on the upper seat, all of which is better for guiding cartridges.
Over time I will find out if PLA is more suitable than PETG or if NYLON is best.

It is better to print slowly, for example at 50% of normal speed and with a layer height of 0.1 mm.
PETG Aurapol temperature 243 °C and bed temperature 85 °C for my 3D print.
