Martello universal coffee capsule

I own couple Martellos coffee machines for years and since then I am trying to buy universal capsule, so you could refill it with own coffee brand.

PERHAPS IT WILL SUIT ALSO FOR:
Julius Meinl -ESPRESSO FORTE
Lavazza Blue

I have one machine just for making tea.Why? Because water is not so hot and you could drink it without waiting to chill /cool down.

Please bear with me. This model was tested only with PLA because I ran out of ABS filament.

I WOULD BE REALLY GRATEFUL FOR FEEDBACK
