Consider showing your appreciation by leaving a tip or making a donation on my website: http://ferociousdesigns.co.uk/ if you enjoyed this design! Your support is greatly valued! A straightforward printed alternative to the flexible Z couplers that come pre-installed on the Anet A8. They may potentially enhance print quality, depending on how subpar the original couplers were on your printer and how straight your Z lead screws are. They feature a 5mm hole for the stepper shaft with a flat and an 8mm hole for the leadscrew. There is a 1mm section removed from the center of the cylinder to allow for tensioning. It's recommended to use nylock nuts to prevent them from coming loose. I used four M3x10mm bolts for each and four M3 nuts (since I didn't have enough nylock, I mixed some standard M3 nuts with the nylocks). Printed at 25% cubic infill. Supports shouldn't be necessary.
