Have you ever had newly fletched arrows stick together because you leaned them against the wall to cure and the vanes touched, or they fell over and messed up your fletching?
Ever glued points into a new set of shafts using epoxy and then had trouble standing them vertically to cure? me too. This solved my problem, easy to build, should have made it years ago.
350mm long 200mm high, Base is 70×19 sides and top are 40×19. Holes are spaced 25mm apart, if you use high profile vanes you may need to increase the length and hole spacing. Build one, you’ll love it.
