This Oldham coupling is made of brass, which reduces friction and has sufficient strength. CNC machining controls the clearance at the connection location. The use of this shaft coupling for the Z-axis screw of the 3D printer will reduce the printing quality problems caused by the swing of the hot bed during the printing process.

Raven3DTech went above and beyond, they were onsite to assist with any issues and solved immediately. They sent the item out that afternoon to ensure I get the package without delay. Highly recommended site with genuine customer care. Thanks guys

Really good cusomter service and quality products!

Raven3d is literally your one-stop shop for any 3d printing-related needs. The owner is very knowledgeable about the things that you might need for your setup because he also occasionally builds printers for customers and you can also ask him if you want a finished printer. Shipping is also very fast. I am extremely happy with their service. Don't hesitate to buy from them especially if you're in Australia of course. Which I am not but still I buy my parts from them. 😉

Outstanding customer service and support and the prices are comparable with overseas vendors.
I'll buy from Raven over others due to the past and continued service I receive.
