In order to save some space on my desk of my "home office", I've made this little mount for my Dell monitor (U2518D). Currently it's used with a Carbon X1 (6th?) gen, but it has been designed for my next workstation, a Dell Latitude (most recent model).
The concept is pretty simple and I attach a STEP file so feel free to modify it for your needs.
Printed from PETG, .20mm layer height - nothing special (no supports)
*Note: It has been designed to hold the laptop in the highest position of the monitor.
