Printing and assembly

1. Print Spinner.stl, SpinnerLid.stl, SpinnerBottom.stl and SpinnerRack.stl. Also have the spring ready.

   

2. Take the rack and carefully wedge it around the bottom at its slot. There may be some flexing necessary to get it to work but be gentle.

   

3. Place the spring around the peg on the base and as the rack gets pushed in around the peg at the base of the rack. Test the connection a few times by compressing and releasing the rack.

4. Place the spinner on top of the rack mating the spinner's peg into the holder for it in the bottom.

   

5. Firmly attach the lid, being sure that the lip goes in to the bottom all the way around. The fit will be tight which should prevent the need to use any glue to hold the parts together.

   

At last the spinner is ready to use to generate random numbers.
