Since the T-Markers by filmsticks were backordered and i had to go back on set, i decided to design and print my own marks.
I used PolyTerra PLA for my T-Markers, you could try to print it in TPU (maybe feels a little closer to “real” ones).
They are definitly not build to last forever, especially when you consider how they're getting used on set. But if you're in need of cheap T-Markers and need them fast: they just work.
