Solar light spike

I needed some square spikes for my solar lights so i thought why not just design one! So i hopped into tinkercad and made this up using the only spike i had left to measure. it should be about 7inches long and 1inch wide at the square support. my solar lights are chained with a cord so i also included a notch for it to go through. I'm not sure the best orientation, filament or settings just yet but feel free to give me some feedback on what worked best for you c: this is the first model i've ever made that was worth sharing so i was very excited to share it with you!
