Update : Following further feedback, I've created a new version for the 250x250mm printer, which you can find here : https://makerworld.com/en/models/478459#profileId-389671

An interpretation of the Ikea Skadis board with infinite size possibilities, featuring invisible screws and a design aimed at using less plastic for a more economical print price.

For example, you always need to print the A, C, G, I plates, you can use these four plates to create the smaller size.

If you want a taller one, simply print two, four, six… plates D, F for a taller size like the picture.

If you want a larger one, simply print two, four, six… plates B, H.

And if you want a bigger square, print all and add more B, D, E, F, H to complete your desired size.

To fix the plate to the wall, use screws with a diameter of 4mm. For my assembly, I use TX20 screws to fix my plates in the wood.

FYI: It may be cheaper to buy the original Ikea Skadis.

But if you're far from an ikea store, are interested in the screwless design and just need a small modular format, then my design may not be so bad, I tried to design it with the minimum of plastic needed to reduce the final cost and get closer to the ikea price for a similar size.

Personally, with 1kg spools I bought for 20 euros, the final cost of my print cost me around 13 euros, compared with 10 euros for a skadis of the same size currently on sale in France (02/2024).
Sure, it cost me more, but it suited my needs, so it's up to you to choose the best option.

Printing can also be messy, so for best results I recommend printing the first layer slowly.

Happy printing :)
