Standoff for 5/8 inch (16 mm) tubing

prusaprinters

My water softener has an overflow drain tube.  I needed a way to position it above the floor drain, while maintaining an air gap.  I designed these standoffs to hold the tube in place at an appropriate height.The screw holes are all just over 4 mm in diameter.  I used M4 x 8 mm screws and M4 nuts to hold the clamps closed.  I used #8 x 1" wood screws to attach the standoffs to the floor.I printed it using PETG with 20% infill.  The lower part needs supports, but the upper part doesn't.
