Styrofoam Anchor

thingiverse

This is a printable anchor for use on Styrofoam house insulation. The design is highly customizable, allowing you to fit it perfectly to your specific size and needs. It's designed to be easily printed, making the process quick and efficient. The anchor features a large coarse screw that securely anchors it in the soft Styrofoam. Inside the anchor is a hole where the actual screw can be screwed in tightly. You have several options for printing an inside thread - you can either print one manually or use a self-cutting screw. Tests conducted on a small 15mm diameter and 40mm long anchor showed that it takes more than 10kG (100N) of force to pull it out by hand. This demonstrates the anchor's exceptional holding power. There are several examples available in STL format, with file names clearly indicating length, outer diameter, inner diameter, and flight specifications.
