This is a remix of https://www.printables.com/model/109546-apple-watch-duo-charger-also-single-charger/ . The original duo design has been modified in a trio with two Apple Watches on the outside, and one Samsung Galaxy Watch in the middle. The bolt size is also changed (based on what I had lying around, M10), but these can be easily modified to suit your own needs. This is designed from scratch yet very closely follows the original design. The STEP file is also included for easy modifications to suit your own needs.
For my own needs, I printed with gyroid infill and paused the print halfway up to fill the stand itself with sand. This together with the bolts gives ample weight for a very stable stand.
