The model
Head sleeve, two scissor arms with two links each and the nut piece come off the bed already connected. The hinges are pin hinges made of stacked knuckles with 0.4 mm of air between the layers and 0.35 mm around the pin. As you tighten the screw, the nut piece moves forward, the knees fold outward and settle behind the board.
For the 18 mm drill hole there are two lengths: W12.5 for a single drywall board and W25 for double cladding. Print plates with four anchors each are included. The screw (wood screw 4 mm) cuts into the nut piece.
