D1 to Uni Power Tank Refill Converter
thingiverse
这个套件可以把任何D1规格的笔芯转换成三菱PowerTank的规格。因为这个笔芯已经停产了，而且很不好写，所以我自己也是换成了ohto的针尖芯。This tool will convert any D1 refill into an Uni-ball PowerTank refill. I did not make the hole very tight to have better tolerance for different types of material. However, if it is too lose, you can put some tape on the refill to fix it.
