Modular Shoerack/ shelve

These are the printable parts for a modular shoerack I designed to be as sturdy as possible with as little effort and material as possible. The whole design uses the printed parts according to the List, 4 18mm (by 300mm wide) thick wood boards according to the dimensions you like, as many wood sticks with 14mm diameter as you want, 4 Nails for security 2 pieces of 4-5mm thick rope and some screws for peace of mind if you want (I didn't used them). And a 5 mm drill bit for the holes.

I reccomend to print all the parts in PETG or any other material not creeping under load as much as PLA as  you will have constant load from the tensioned ropes in the back.

Parts List (printed) all printed with a 0.4mm Nozzle:

4x Shelve_edge

     - reccomended to print on the flat side and solid (around 6 Wall lines at 0.8mm should do            the trick) at 0.25mm layer height reults in 11 bottom layers. 22g of filament

4x Shelve_edge back

     - same as the front edge but i reccomend to print 22 bottom layers so the part is solid                  around the rope. 20g of filament

4x shelve_bar_attachment for every level (two for each bar/ wooden stick)

     - lay it on the 45° slope so it can be printed without support and the pin has layers at 45° as        well so it doesn't shear of as easy. print with 5 wall lines and no infill and top layers                    needed. around 3.5g of filament you should be able to fit at east 9 on a 200x200 printbed.

       I used a little dab of wood glue to stop it from twisting once on the shelve thetolerances on        my drilling were to bad to fit an attachment with two pins but i challange you to drill more        accurate and deign a proper two pin attachment.

2x shelve_tensioner

     - print it standig up on the larger surface with 4 wall lines and no infill/ top layers, makes            for a strong enought part. 10g including the wedges

4x shelve_tensioner_wedge

     - print it on the flat side, thats the side it will slide on in the tensioner. Print solid for best              results. around 2g for both wedges

1x shelve drilling template (not entirely necessary if you don't need the full flexibility)

     - print it upright or at a 45° angle to ensure that the pin doesn't shear of as easily. It is not            entirely necessary you could also measure out the singles holes and drill them only were            you need them. I also found this not to be very accurate along the whole lenght. 10g of              Filament

Assembly:

The assembly is very straight forward when you have upright boards drilled. Just put them all together with the printed edges in place. Make shure that the horizontal boards are laying on top of the vertical ones. Then get the ropes in the back edges and tension them using the printed tensioner (watch out this is the step where you should check that the shelve isn't skewed). Then fix the boards together on the front with small nails form the the top/ bottom. Now the shelve should be reasonably stable depending on the tension in the ropes but don't expect it to be perfectly stiff as there will always be a little elasticity in the ropes. Now you can move the shelve around as you please and put in the bar attachment (with a bit of wood glue) and the bars/wooden sticks.

Feel free to leave any design suggestions and improve on the designs I provided here, if I make any changes I will update the files here. For now the shelve was at my antrance for a few weeks and seems to hold up perfectly.
