I must be quite honest, I'm quite hooked on complex fidget toys, so this one caught my attention and I had to print it. I've printed 3 so far using red PLA as the base colour and printing the shutters in grey and black. The print file provided worked well, I printed them on my Hi using Ender PLA with no issues, I've added the print files for anyone who's interested. I did print mine at a lower print height (0.16mm) which obviously meant my prints took longer. Its a fantastic fidget toy, I haven't put it down, I highly recommend it.
