Tutorial on how to assemble the mechanical components of a DIY split-flap display module.
The rough steps are:
- separate laser-cut parts (0:12)
- remove protective film (0:34)
- Spool:
- put together spool struts (1:31)
- attach bolt+nut to spool retaining piece (2:16)
- insert spool struts into spool disk (2:50)
- press other spool disk onto spool struts (3:25)
- check magnet polarity and insert magnet into spool (3:40)
- pass motor through side hole and secure with 2 bolts (5:05)
- mount hall effect sensor module and secure with a bolt (6:02)
- press spool onto motor shaft (7:15)
- press fit bottom piece into left piece, with laser-engraved lettering facing up and circular hole toward the back (7:50)
- press fit top piece into left piece, with circular hole toward the back (8:14)
- press right piece into top/bottom pieces and aligned with spool axle (8:34)
