Kingdom Tracks Leg Panel Locks

This is a pair of small parts to lock Kingdom Tracks' outer side leg panels in place in bot mode. 

The parts install inside of the legs and add a new tab that plugs into the clip on the back of the wheel. They must be removed and set aside when transforming to car mode.

These parts and printable STL files are also available at JRC Design Store.

Installation Instructions (see photos):

1. Swivel the leg side panel 90° to reveal the interior of the leg below the knee, and open the gray shin panel slightly.
2. Insert upgrade part into leg, making sure the edge towards the back of the leg is locked under the corner tab on the blue back panel.
3. Close gray shin panel.
4. Swivel leg side panel into its normal position. You may have to pull it out a bit to get it past the tab on the upgrade part. 
5. Rotate wheel until the slot in the wheel clip aligns with the tab on the upgrade part.
6. Press the leg side panel into the leg to lock the tab in place.
