Worked straight off the printer - no cutting, filing or sanding needed, great design. The knurled handle shows amazing detail, an excellent design. Printed using "Galaxy Blue" PLA from Faberdashery which gives it a well deserved sparkle :-)
Initially, I used the loose version of the clamp protector and found the original one impossible to attach. However, I persisted and after placing the screw component in the freezer for 10 minutes in an attempt to get it to contract, the clamp protector snapped into position nicely and is now loose but not so loose that it will come off with a slight tug which was the case with the loose protector.
