Modular Shoe Rack

I have created this modular shoe rack to organize our footwear better. 

The whole model was designed to be modular and customizable in width. The framework is 3d printed from PLA and takes in five wooden round rails of 19 mm diameter per compartment.
Depending on your location you can use these examples (DE: OBI, Bauhaus) or anything similar. Make sure the rails don't fit too tightly. If you cant push them in relatively easy sand them down using some sandpaper. If you try to squeeze them in too hard the layers of the frame might seperate!

The model measures 300 mm in depth. There are two sizes for the frame height: 150 mm and 200 mm. You can stack them modularly however you please and need. For the top compartment there is also an endpiece to give the whole rack a rounder appearance.

TPU feet for a softer stand are also included.

Printing and Assembly

To print the model you should get an exaple wood piece that you plan to use. 

Test: I included a test part on plate 5 to verify the measurements.

1. Start by printing one compartment by printing the same plate (plate 1 for 150 mm, or plate 2 for 200 mm) twice.
2. Cut the wooden rails to the length you want your Rack to be. You will need five rails per compartment. Please note that 28 mm of the rail go into each side of the frame. The total width of the rack will be the length of your rails + 4 mm. For cutting I suggest using a stopper so you can always adjust your rails to exactly the same length. Make sure you sand down three centimenters at each end of each rail untill the glide in with some resistance. 
3. Then mount all five rails to one side of the frame. Make sure they all went in the same depth.
4. Place the other side of the frame on the other ends of the rails. I mounted with the rails pointing up and used a piece of wood which I hit gently with a hammer.
5. Repeat steps 1. to 4. for each compartment you need. Make sure the compartments couplers on the frame bottom fit into the slots on the top of the other compartments. Don't clip them in before making sure the setup is correct. The clips are tight and very hard to remove.
6. Print the end pieces by printing plate 3 twice.
7. Print the TPU feet. I suggest printing them by object for optimal quality, however I included a profile for people whose printer can only print by layer.
8. Assemble the whole thing by placing the rack compartments on top of each other and gently hitting it from above (I used just my fist) until they clip in.
9. Place all the footwear you have in it. If you run out of space: EXPAND!

Voilà: Order in the shoe section!
