- Make sure that Your printer is calibrated well before printing.
- Do not fix syringes too tight because glass will bend a little and it will create a lot of friction inside.
- Pistons must be polished with fine sandpaper to move freely inside cylinders, but without losing too much pressure.

I have printed it with PLA but the base was not stiff enough. STL files have been fixed a bit to help with that, but printing the base with ABS may be a good idea.
