POTA20_large_spike

Great design by nasaprntr (https://www.thingiverse.com/thing:6893324), but I wanted to use the larger 7" spikes. The white object on the left in the photos fits the larger spikes. The tolerances could be tightened up a bit on the spike, but it works well for me so far. Fits inside the bottom of the POTA20 mast bottom section once you remove the bottom threaded cap. PETG, default “generic” settings, 4 walls, 60% infill.
