Knife blocks, the birthplace of bacteria. Every so often you need to change yours and they always end up taking up costly kitchen counter space. Have a spare shelf in your kitchen left and want a unique item? This hack will help you out.
Print the files at a Hub in your neighbourhood or on your own printer. PLA would be the preferred way to go. You will probably lose durability compared to ABS but PLA makes for a safer choice since it is biodegradable. Slightly heating up your printer bed is recommended, but pay close attention to the first printed layers to make sure they cool down fast enough. Once printed, take the knife block and shove it into the cabinet. Some additional support material might be needed since it is not a very tight fit.
