Hi - printed well (wedges needed a little fettling) works a treat – had to use the original aluminium clamp as a spacer under the RHS to lift it slightly to get the belts parallel – thanks for a great design.

Thank you for your tip with the spacer. I think this would make it possible to use a 16 tooth GT2 pulley on the motor and keep the original bearing idler. Thanks.

Hi - correct - I hadn't noticed that it was for the 20 tooth pulley - works great with the 16 if you use the original clamp as a spacer.
Next up is to sort the Y axis – unfortunately I can’t use your design as I don’t have the clearance on the right hand side due to an aluminium brace between the motor and the idler bearing to prevent the carriage bending and misaligning the X axis linear bearings when you tension the belt.
