Magnetic End Delta rods

I had 200 mm carbon fiber rods and I needed them to be 268 mm (for my delta Anycubic linear plus) to use them with duet smart effector.

They should fit rods with a 6mm diameter (I used a caliper and the exact diameter is 5.9 mm) and magnets with a 12 mm diameter (exactly 11.9 mm). The magnets are 3.7 mm high.

I printed them with 100% infill and 5 shells
