I designed this model for #DIY Back to School Contest. At school and now at work I always have the difficulty of finding a diary and notebook with a cover that represents my love for cats and with a positive message that brightens up the day. In my country it usually sells diaries with a neutral cover or with a comedy that doesn't represent me. Online it is also possible to customize the print, but it is almost always sold out and the prices are too high. To finally solve this problem, I designed a cover that can be 3D printed without supports and that is to be applied on top of or instead of the real one of the diary. This model corresponds to a small diary but with any modeling program it can be scaled and adapted to your notebook. It is formed by a central part that allows the fold and the opening and 4 slots on the back to insert the closing elastic. The decoration and the cover have different thickness to allow a manual change of the filament during printing to obtain a two-color model. Have fun and make your days colorful! Be Pawsitive!
