Step 1: Print the Enclosures

Attached are 3 parts that you will need to print out on your 3D printer.

Step 2: Cutting Threads

Use M6 thread cut on the aluminum rod.

Step 3: Start to Half Assemble It

Thread the shaft in the bottom 3D printed part. The printed part hole is slightly smaller and the aluminum rod will self thread the 3D printed part.

Step 4: Attach the Magnet

Use screw to attach the magnet. My screws were a little to long. I cut them to length so that the aluminum rod and screw have little room between them and can be tightened.

Step 5: Cutting to Lenght

Assemble and add the top cap. Mark on the aluminum rod the top of the cap.

Cut the rod on the mark and cut threads there to.

Step 6: Assemble

Connect all parts and that is it!
