Name Badge Clip for 4x3 inch name badge sleeves.
Had some fun with this one, i never use the retractable lanyard. I would tape the top shut to secure all my cards inside. Figured it would be a perfect solution for 3D printing.

Reference Slicer screenshot for print orientation, no special settings, post processing includes cleaning up some edges so the slider moves freely over the two clam shells.

Stay tuned for modifications and more sizing if demand calls for it
