Foldable laptop desk for armchair
Got tired to neck pain caused by sitting with laptop on lap. Fortunately I had chair with pretty straight armrests and I could use it to support desk without any permanent damage to the chair. Gap of the frame is tight fit into armrest (inner width 90 mm) and it supports weight of laptop easily without sliding off. I placed a piece of anto-slip mat between to make it more steady.

Materials
~15mm thick sheet of hardwood, plywood, etc. Parts nest size ~70*60cm
8mm bolt, washer and wingnut as axle. 1 thin large diameter steel washer between top and frame.
Tools
Shaper, miter saw, domino router, router, eccentric sander, etc. general woodworking tools.
Instructions
You probably need to adjust frame slot width to fit your chair. Make it tight, but not too tight ;) Cut parts from sheet with Origin. I used 8mm roughing bit + 6mm for finishing pass. I used old recycled 26mm thick walnut tabletop sheet. I cut shapes 22mm thick and thinned sheet to final 15mm with several passes. Final planer pass from downside removed parts from scrap. Frame parts are drawn with outer length, cut them to 45 degree miter. On frame top part, there is also extra material, cut it out after assembly. It is easier to get side profile round this way. Use 4mm dominos to miter joints. Straight support piece on from lower end is missing from shaper file, make it conventional way. 8mm dowel fits there nicely. I rounded desktop underside as much of possible to make it look light and save some weight. I did not cut axle holes with origin. Wanted to make mock-up installation, since altering axle position affect ergonomics. In my case axle is about 2 cm inside from frame front edge, this also lowers the risk of breaking. I stained wood black and waxed it over. Nice open pore surface was a bonus.
