Ultimaker Print Core Holder Customizable

thingiverse

This is a highly adaptable Ultimaker Print Core holder. You can easily adjust the number of slots both horizontally and vertically to suit your needs. The hook's position is also fully customizable, allowing you to place it on either the left or right side, at the back, or choose not to have one at all. Typically, printing with the back side down doesn't require any supports; however, if the hook is positioned at the back, supports will be necessary for a smooth print job. It's worth noting that the dimensions of the hook are fully customizable due to the variable thickness of Ultimaker side panels - my printer, for example, has a thicker panel on the right side than on the left side.
