WEBLOCK for 20mm webbings

Weblock for 20mm wide webbings. WLL: 3kN. Parts: - printed weblock-body - D-shackle 8mm stainless steel source: https://www.slacktivity.ch/de/catalog/product/view/id/2112/s/d-shackle-8mm/category/80/ - Aluminium pipe (>AL6000) 15.5x1.5x50 Press the alum. pipe carefully into the weblock-body. It helps to heat up the body by a heat fan, so it can adjust to the alum pipe nicely and keep sticking into the weblock body. Breaking strength tests: - PETG weblock-body: 7.53kN - PLA weblock-body: 7.23kN - Continue breaking strength test with broken weblock body but intact aluminium pipe: 12.05kN V3: until 6kN only slight reversible formation. In the breaking strength test, the sling has broken by the sewing on 14kN. The weblock was deformed - but held strong. I recommend PETG before PLA. Because PETG has a more uniform static than PLA and the higher melting point makes the weblock longer lasting concerning friction based excavation from the webbing tensioning. Printed without support. This turns out in a bit ugly surface under the center diverter. But this will be smoothed after tensioning the webbing a few times. Tensioning gets better with every time you use the webblock. 26.02.2019 UPDATE on the 3d-design: - stronger bow structure - nicer to print without supports 28.10.2019 UPDATE on the 3d-design: - stronger bow structure due to better layer orientation
