About this 3D model
Created a tank key for IDO Seven D toilets. Fits to the toilet's two sided flush button and opens the rod that needs to be remove before opening the tank. Has a 15mm hex, with a bit holder at the bottom. IDO Z6205700001 IDO 5731280 WC tank key. The smaller version worked great for me. The longer version might be a bit easier to use. An original version of this costs a whopping 19 € in Finland for a little plastic hex key. Only printed the shorter version. Printed with following settings: 0.24mm layer height 15 % infill 5 bottom layers I used no supports but I do recommend using supports . Bambu Lab P1S managed to do pretty well without supports.
