Couldn't be bothered always picking my phone charger off the ground to put into the phone, so I made this with OnShape. Printed with 20% infill on its back within Simplify3d with no raft. You will need to make sure you have supports.

The holder fits the Samsung Note 10+ with the clear case it comes with in the original packaging and the Samsung original charger fits tight into the bottom section.

A phone with a similar case may also fit. The bottom allows for 12mm thickness and the top drops a little tighter to 10mm to hold it snug in place.I attached the holder with heavy duty double sided tape to my bedside table.

Took my Ender 3 1 hour and 12 minutes to print at .2mm layer height

EDIT: I've uploaded a version for the official Samsung standing case. Dimensions of fit is 81mm x 13.4mm (w,d). If you do print this, can you tell me how it fits. I've estimated the charging port location by looking at images.

Thanks
