Wacom Intuos Pro Pen 2 Nibs 80pcs Lifetime set

Nibs for Wacom Intuos Pro 2017 tablet . Made those for myself half of year before and they are perfect !  They have better sliding than basic or felpt nibs and have way more durability than standart . As for me those 80 pcs are simply lifetime set of nibs .  I did them because those that come with tablet wasnt last too long , and feel from them wasnt as good as i wanted . So i made those and checked it in all materials Shapeways can offer (basically 8 of them) . This material i set as default - best one for nibs  .  Feel from nibs more like silky and still very firm .
  Before you can use them you must  cut them off base and use some sandpaper - because it is have a bit more material than needed to fit in your pen . so you just grab it and turn in your fingers to make it more smooth and round . i found there more like 20-40 moves depending of your sandpaper grit number before it fits freely in my pen . it will take you not more than 2 min - and will last about 1-6 month per nib :)

 UPD
So i use those nibs for 2 years . here some photos of my tablet and those nibs in real life :) no scratches - surface become polished in middle to almost mirror condition .
