The hands on this model are free to move.  Use them to teach your child to tell time or hang it on the wall to mark when something is supposed to happen.  We put one on our daughter's door to remind her when she could get up from her nap.  We put one on the outside of our bedroom door to remind her of the earliest time she could wake us up on the weekend.

Version 1 (Retainer clip):

Instructions:

• Print the face with a single color change at 3mm.  If you don't have an MMU, a manual color change will still work.  
• Print the hands in the same color as the numbers on the face or a contrasting color. 
• Assemble by putting the hands over the post and locking them in with the two retaining clips.
• (Optional) Hang it up with 3M command strips

Version 2 (Screw):

Instructions:

• Print the face with a single color change at 3mm.  If you don't have an MMU, a manual color change will still work.
