This improved top corner support for the Ikea Lack table is perfect for building an enclosed space for your Original Prusa i3 MK3 3D printer. The modified design provides a more stable and secure fit, reducing the risk of tipping or breakage. The support is designed so that the original double-ended screw from Ikea Lack can be used for mounting between table legs and table top. Assemble the table as described in Ikea's instructions, but with this support clamped between the leg and the tabletop for a stable and durable setup.
