Shelves compatible with "ZURU Mini Brands TOYS"

I got inspired to design this shelve from scratch when our daughter got the “ZURU Mini Brands TOYS” (https://www.idealo.de/preisvergleich/OffersOfProduct/201727663_-mini-brands-toys-30280-zuru.html) Store for christmas but there were shelves missing (on purpose - they are displayed in the instructions but labeled “not included”) which you would need to buy separately. Unfortunately we did not find those as well so i decided to print some shelves. 

As seen in the images, the shelves have different mounting on the baseplate, so i came up with a solution which you could place in both of them (proven by the images as well). The shelves are very good secured in both locations but are also combined together in groups of four with this top piece which came with the market.

The shelves with the black bottom and back are the ones i printed - the shelves with the blueish bottom and grey back are the original ones. Feel free to use those exact colors if you have the matching filament. I would love to see a picture of your prints, if you end up doing so, as i don't have them at the moment. 

With that said - i really hope you enjoy those shelves. If there is anything i can optimize with this design, please let me know. 😊
