Shavings will be present which should cling to our wrap. To avoid potential damage to the extrusions each is individually wrapped and then wrapped together before cuts or drill/tapping are done. This USA finished aluminum T-Slot frame for the Voron 2.4 Frame kit comes with everything you need to complete your frame - including all required screws for blind joints (M6 for frame! If you're buying West3D's fastener kit enjoy these extras!) If you wish to use Corner Cubes (like OpenBuilds) instead of blind joints be sure to add them to your cart.
