Spiral Christmas Tree Replacement Parts

These are some replacement parts for some spiral decorative Christmas trees. The plastic spikes used to ground the center post tends to stay in the ground upon removal, never to be seen again. I designed these with some geometry for easy gluing. I hope they never come out of the posts again. I also included some stakes to replace lost or broken ones.

17.3mm spike for larger diameter posts
8mm spike for smaller diameter posts
Stake to secure monofilament l
