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!
