Carefully cut out the viewing windows in the holder.
Cut small slits over the red dots on the holder (both sides = 8 cuts). This is where the paper fasteners will anchor each wheel.

Shorten the tabs on four paper fasteners with a pair of clippers. This is optional but we think it looks nicer!


Use a ruler to gently score (but not cut!) the fold line on the holder.

The holder folds easily and neatly after scoring.


Pierce a paper fastener through a tab on one side of the holder and through a wheel.
You can assemble the Resistor Helper with either side as the “front,” but we think you’ll use the 4-band side more often.

Pierce through the opposite side of the holder and flare out the tabs on the fastener to secure. Repeat with the other three wheels.


Once you’ve verified you assembled the wheels in the right order, carefully glue together the corners/edges of the holder.
That’s it! Use and enjoy!
