Created a simple click-on-hook for my balcony so I can guide my plants and x-maslights.
Also added a double design so you can print two at the same time if you have a small printer like me; A Mod-t.
I use rafts because the Mod-t like to warp a bit on its non-heated printbed.
Shell thickness 1.2mm for best results.
My balcony pillars are 10cm by 2cm.
I used Sketchup to design this balcony-hook-thingy.
