The author remixed this model.
Thanks to https://www.printables.com/@VPoP_506593 for his nice tweezer's holder. They were extremely exact to the Ikea skadis board, so I remixed it with slightly easier overall sizes, which makes it a breeze to attach it to the skadis board.
Also smoothed out the front side, as there were two edges which makes printing not so easy.
Thanks :)
