Human: FIXATION BY INSERTION OF A CLIP Where the panels are tightly wedged between the insert and the piece to be fixed, resistance on a soft material plate such as polystyrene is limited to the resistance of the plate itself. During screwing, the insert can be held in place by a 13mm flat key or a pliers, the threads (rep3) then perform an anti-rotational function. Placement (photo 3): 1. Screw a screw into the insert to form a mesh to avoid applying too much torque during screwing. 2. Perform a pilot hole using a drill bit smaller than those of the insert, hold the insert with a 13mm flat key or pliers to start screwing. 3. Screw enough to slightly insert the head of the insert into the material. Material: Wood screws of 3 mm Recommendation: Print in ABS FIXATION BY INSERTION OF A CLIP The proposed inserts are not designed to bear loads, for example they have been made to create a children's toy from polystyrene plates or equivalent soft materials. The inserts are immersed inside the soft material plate, they work on the principle of a harpoon, the placement of the screw between the teeth (rep 1) spreads the two wings (rep 2) in the material. Placement (photo 4): 1. Screw a screw into the insert to form a mesh to avoid applying too much torque during screwing. 2. Perform a rectangular pilot hole using a drill bit and a size smaller than that of the insert 3. Immerse the insert inside the plate, the insert must be at least 5mm away from the surface of the plate 4. Screw the screw in final position with minimum tightening. Important: The insert must be sufficiently immersed inside the plate, the top of the insert must be at least 5 mm from the support surface, it must almost disappear visually. Remark: This variant is faster to install but less effective. Material: Wood screws of 2.6mm to 3mm Recommendation: Print in ABS Material: - Wood screw of 2.6mm to 3 mm - Screwdriver (Option: flat key of 13 or pliers)
