Anti Z-Wobble for M8 Lead Screw - Geeetech I3 ProB (not for Anet A8)

This is another Anti Z-Wobble accessory. I wasn't satisfied with the designs I found on thingiverse. I've tried 2 of them and it was necessary to post-process them with sand-paper or a file.

V1 uses 2680 mm filament / 2pcs
V2 uses 1560 mm filament / 2pcs

V3 is the most lightweight and
