Replacement Yard Spikes that don't break

thingiverse

So every store sells these little solar yard lamps with flimsy spikes that are prone to breaking. If they don't break, they sit so low in the grass that they disappear and then I have trouble finding them. This one sits higher up in the grass but not so high that it gets mowed, is solid and easy to drive into the ground, has a screw hole for mounting the spike to the base plug, and fits the lamps I buy which are 21.4mm in size. It may not fit the lamps you buy, so feel free to modify the plugs if this is the case, as long as you're not a retailer trying to figure out how to fix your awful spikes.
