This is the bedclip of Rostock Nano. Rostock Nano is a compact delta printer. https://www.thingiverse.com/thing:2764097 The design of this bed clip is straightforward and uncomplicated, making it easy to create. However, with this clip you can firmly secure the bed and beam in place. Using this bed clip is simple and intuitive. To fix it securely, simply hook onto a beam and slide it into position. The thickness of the glass plate has been modeled at 5 mm, but adjust the Y axis scale to suit your specific printing environment. In my previous setup, I used metal clips, but sometimes the glass plate would shift or move.
