connections for shelves

cults3d

I needed a shelf to put my seedlings as I have a lot of them, so I decided to make the parts in 3D to easily create my shelf with purlin slats of about 35/18 mm and my two 18 mm thick MDF boards. Only downside, the legs I had made initially are thin and cracked a bit when I screwed them, so I modified my stl to get you stronger legs. on the pictures, the bottom parts are printed with a less important thickness than my modified top parts, but as it holds I have time before redoing my bottom parts ;-) I made holes for screws that are 5mm in diameter
