Disposable vertical tattoo cartridge holder

There are cartridge holders out there that you can buy for pennies but if you need one and don't have one on hand this might help you out.

This version is vertical and I use it to keep my cartridges safe when practicing or using it them for leather or second skin. 

I made it to fit any cartridge with the lip that I could find but just in case I made a a tester so you can trying just that slot to make sure and not waste filament and time.

Biggest advantage of these over the regular one is that you can put a wee container under it being ink cup or anything really fill it with clean water or whatever solvent works with ink or paint you are using it with and stop needles from drying out.

Obviously, if you tattoo people these should not be ever reused and I they should be sterilized before use.

Btw these are the ballpoint tattoo cartridges I use they are quite good at learning the right pressure as too little and you don't draw anything and too much and you ruin the paper.
