Semi-permanent Desktop Panel Extension Board

I want to put the A1 in an enclosure inside the wardrobe.

The wardrobe isn't deep enough, but if it were extended by a section, it would be just right. I couldn't find a similar model, so I referenced

I designed my own version. PETG printed, its strength appears good, and it fits perfectly. I tested it, and it can extend various tabletops and bed boards.

=====Detailed specifications below=====

Panel thickness is 4mm with spiral infill, just enough for a full rotation.

It has 2 3mm countersunk screw holes for semi-permanent fixing, or you can use double-sided tape.

The support thickness is 21mm, matching most boards. Grid merge infill slightly improves printing speed.

There is a 1mm thick, 4mm wide groove at the joint with the board surface, which perfectly grips the board's edging, ensuring flatness and aesthetics.

Additionally, I made versions without edging on the sides and front. Choose as needed.
