This is a very easy printed tiny whoop size quad gates .
You only have to print this two parts and make the gate and the support by any less flexible tube that has an inner diameter of 8 mm . I used the black tube that we use in automated gardening systems.
For the gate u need to use 1.20 meters of tube and after u heat the end of the tube you puss them in the connector for a tide feat.
For the support of the gate use 4 x 30 mm tube and after u heat the tube ends to get soft puss them in the cross base .
If your tubes are curved use hair dryer to make them straight .
