v1 model is here
My son seems to ‘lose control’ of the lawnmower and tends to hit my landscape lights with the wheel, causing the brittle spikes to break off at the base so I designed my own version that's a little more robust.
Designed for 18mm tube (I.D.) and has a recess for wiring in case you have low voltage lighting like I do.
This model adds a slot so that the damaged spike can be replaced without having to disconnect the wires.
The author remixed this model.
Added a slot for wires to pass through so that they need not be disconnected
