Garden Fence Post
This is a simplified post compatible with the great thing(http://www.thingiverse.com/thing:28976) created by TrevM.
TrevM's post consists two parts and looks very elegant. But I don't want the posts to appear above the ground, so its elegance is totally a waste to me. The simplified version uses less filament and combines the post and the panel together into a single print.
By the way, if you have loose nut problem as I had, try use a soldering iron to melt the bolt and the nut together. It worked perfectly for me.
