Fully 3D Printed Laptop Table Hanger. Yes, you can buy something like this, but now you can also print it.

Was designed to sustain ~20 kg clamping force and at least 5 kg of payload PER HOOK with a minimal deformation. As much as the form factor and material properties allow. Requires minimal assembly after printing.

Happy printing!

Can be printed from PLA or PETG.

Hook-HookSplit.3mf and ClampSet.3mf are prepared for printing batches of parts.

Hook

For the Hook go with minimum of 30% infill, 3 perimeters and rear seam alignment.
Generally you don't need supports when using splitted hook parts. Depending on the printer, overhangs for splitted fillets might fall a bit, but they are not structural and mostly even not visible, so it's up to you to check if you need supports for HookSplitFront.

If you going to split hook from monolith model, then it must be split on two or more parts to avoid a lot of supports.

The complete hanger consists of two hooks. When printing the second hook, don't forget to MIRROR the model.

Clamp Set

For the ClampSet parts 20% infill, 3 perimeters and random seam alignment should work.
ClampSetScrew should be printed at a 15-25 degree angle, with custom supports only under the screw head to keep the threads clean.

ClampSet parts can be printed twice without any modifications.

If you printed pre splitted hook model, you'll need to glue it together. Before gluing, try to combine front and back plates, to ensure that it is possible to assemble and disassemble it without much force.

1. Apply glue to the connection pins and the entire contact area
2. Align front and back plates using connection pins and press them together, preferably using clamps for a few minutes (depends on the glue).

Also, because PLA and PETG plastics are quite smooth, you might want to buy or use some non-slip pads and apply them on clamping surfaces. While the clamp will work without them, it may be easy to pull out by hand. With non-slip pads it will be way harder to do and helps prevent accidental displacement.

ClampSet-ScrewInsert also needs to be glued in.
