Cap / Hat stretcher enlarger for big Heads

thingiverse

I designed this ting because I always had the problem with too tight caps for my big head... Hardware you'll need: 1x M8 stop nut (or use threadlockable) 4x M8 nut 2x M8 washer 1x threaded rod cut to the size you'll need for your head 1x M8x25 nut (a simple nut will do the job too, but its more guided with the long one) If you like this thing, I like coffee ;)
