A parameterized bedside holder for books, tablets, e-readers, notebooks, or slim laptops. The holder hooks over a bed frame, desk edge, shelf, or similar panel. It uses two printed hook bodies connected by top and bottom rails, creating a sturdy open-frame cradle that can be customized to your setup.

The threaded inserts are installed in the hook pieces, so the overall width is set by the horizontal connector rails. To make a wider or narrower version, you only need to reprint the top and bottom pieces instead of the entire holder. This uses a little more M3 hardware and assembly, but saves filament and makes the design easier to scale for larger items like tablets and laptops. The hook depth, hook height, hook width, holder width, and support dimensions are all adjustable.

Hardware required

• 4× M3x6 bolts
• 4× M3x5x4 threaded inserts

Print notes

PLA should be fine for light use. For heavier devices, wider spans, or warm environments, consider PETG, ASA, ABS, or another tougher material. Use enough walls around the hooks, rails, and threaded insert areas. Test the fit and strength before trusting it with heavier or expensive devices.
