Two types of "bearings" are available for download. If your printer prints with minimal tolerance, I recommend printing the V2 model. After printing, the model needs to be folded, the "bearing" simply snaps into the spinner. For easier folding and movement of the spinner, I recommend lubricating both models with grease.
