I needed a support for an EMT prop mount for my Christmas Light Show so I designed this.
It slides over .5" EMT and supports 3 legs to provide cross-direction support to keep things sturdy.
Legs can be any length and are also .5" EMT.
Center pole and each leg supports a #10 self-tap screw.
This specific model is designed to be basically solid with enough layers specified to have very little infill (only near base).
Printed with PETG and it is very sturdy.
