🛠️ Assembly manual

Step 1 – Install the Slip Inserts

Press the two slip inserts into their slots on the underside of the bus body.

Push each insert straight in until it stops.
You may feel a very subtle click or positive stop.

Note:
Slip inserts are 3D-printed parts included with the model. They are designed with a reduced contact surface to minimize friction and allow the axle to rotate smoothly. No additional hardware is required.

Step 2 – Assemble the Axles and Wheels

Each axle shaft has one flat side on its end.
Each wheel hub has a matching flat slot.

1. Align the flat side of the shaft with the flat slot in the wheel.
2. Press the wheel onto the shaft until it clicks into place.
3. Insert the shaft (with one wheel installed) through the slip insert in the bus body.
4. Align the flat side again and press the second wheel onto the shaft until it clicks.

Repeat the same process for the second axle.

Step 3 – Done

Your Škoda 706 RTO is fully assembled.
The wheels should rotate freely and smoothly.

Enjoy — and let it roll.
