Styropordübel - styrofoam anchor 11 cm

thingiverse

I created this styrofoam anchor based on the "Screw" from zmaker1. I printed it with PETG using 100% infill, so support is required. A 0.2 mm layer is possible, but a 0.1 mm layer will bring about a better screw. This anchor is designed for isolated houses that like to have a light, postbox, or other features on the wall. It measures 11 cm long, which should be sufficient to carry up to 5 kg. In the bottom of the anchor is a Phillips hole for use with a Phillips screwdriver. Additionally, there's a 4 cm long 3mm hole for a standard wood screw. If you're using it in an isolated house, you'll need to drill an 18mm hole in the rendering. It's best to use a flat drill bit, screw it nearly all the way into the styrofoam, apply some silicone sealant to the hole, and then screw the anchor down. Let the silicone dry for a day and you'll have a stable anchor.
