Spacer for trapezoidal metal sheets - Abstandshalter für Trapezblech-Montage

thingiverse

These spacers are designed for thin trapezoidal metal sheets like sold at tooms (Trapezblech 2000x906x0.35mm). The dimension of the spacers: base 20x10mm, top about 10x10mm, height 10mm. Purpose of these spacers: prevent deformation of the trapezoidal lines when fixing the sheets with screws. STL-File V9 has some material in the hole to hold a screw. This way spacer and screw may be pre assembled on the metal sheet and will stay in place till the screws are tightened. New: with the help of the negativ form you can a) correct the shape of the metal sheets after cutting b) use it to drill the holes in the metal sheet. At the end I had the following process: 1. Cut the metal sheets to the right length 2. Correct damaged ends with the negative form 3. Drill small holes for the screws using the negative form 4. Turn the screws in the holes just a bit and press the spacers (V9) on the screws 5. Finally mount the sheets on the roof
