Sunlu S4 Dryer Twin Track Shelf Brackets

Reorganizing my printer space and using some of the twin track modular shelving brackets to do it.  These shelf brackets are designed to hug the bottom rails of the Sunlu S4 unit.  Printed in PETG with 4 walls and 10% gyroid infill they have held up well.  The posted print profile has an outer brim, the brackets in teh picture did not and there was some slight shifting causing some layer line, YMMV. I used a .6mm nozzle, but .4 would work fine as well
