This shoe organizer was inspired by the ones posted by JujuGG and Master_Q. I liked the concepts but I needed to create one that I could print on my Ender 2 (150 x 150 mm), using the minimum amount of plastic possible, and quickly, so that I could print many. Then I realized that I had a lot of Amazon boxes lying around, so I decided to use a mixture of plastic and cardboard.
This is a filament-efficient print. It uses around 6 meters of filament per part (12 meters in total) and 2 pieces of cardboard, one at the Top where you put the second shoe, and one at the bottom to help keep everything in place.
The initial design used glue to hold the cardboard parts together, used only 3.5 meters of filament, and printed in roughly half an hour. Then, my girlfriend pointed out that it would be more eco-friendly if it didn't need any adhesive, so in order to save the planet I added some slots where you can slide the cardboard parts.
-Optimize the slots to hold the cardboard parts in place.
-Reduce the use of material and the print time.
Regarding the filament, I used this SUNLU PLA + black filament with excellent results http://s.click.aliexpress.com/e/5ZffKBm
SUNLU PLA +
I printed it using a 0.4 mm nozzle, and 0.4 mm layer height with 0.45 mm line width. I also used 2 outer perimeters and printed at 210 °C, 80 mm/s at the inner walls and 60 mm/s at the outer ones.
Will add more details about the post-printing soon. You just need to cut two cardboard pieces according to the size of your shoes. The cardboard thickness should be around 1.5 mm for it to work properly, otherwise you can use glue to fix it in place.
