Samsung G7 G70B Mount - Tobii Eye Tracker 5

Samsung Odyssey G7 G70B Mount for Tobii Eye Tracker 5

I recently got the ET5 as a gift (30 years.. phew time is flying), but I didn't have a good way of mounting it to my monitor, as the included stick-on mounting bracket doesn't work well with my monitor. Luckily, the G70B has a deep bezel and a pretty large "shelf" on the rear, which is perfect for hanging stuff from.

I made this design to specifically fit even small-bed printers such as the Prusa Mini+, so you should be able to print this on virtually any 3D printer.

When mounted, the ET5 sits flush below the "SAMSUNG" logo and button housing, and the bezel arms are very non-intrusive when printed in the same color as the bezel. The hooks on the bezel arms does not block the screen. Note that this mount blocks the button, but you should be fine if you still have the remote that comes with the monitor, and the mount nor the ET5 does not block the remote receiver.

Print Instructions

• PETG or similar is highly recommended due to its ability to flex, can withstand reasonable temperatures, and isn't very hard and brittle like PLA.
  To be fair, PLA may work well, but I wouldn't trust it.

• 3 Perimeters, 25% grid infill

• 0.10mm Layer height (the small area for the magnetic plate becomes easily invisible on higher settings)

• Brim can be useful if you have bed adhesion issues
  I just use a glue stick to improve that

• 1x Mounting Body

• 2x Bezel Arms

• 2x Back Arms (R+L)

• 2x Screw Caps

Assembly Instructions

Detailed instructions can be found in the PDF located in Files -> Other Files.
Complete assembly only takes about ~3 minutes if the instructions are followed properly and there's no cleanup needed. The 2nd image should be enough to reference while assembling, but I've added a summarized instruction for assembly here:

1. Remove any printing artifacts, brims, supports, etc. 
   There are no need for brims or supports on a decently calibrated printer.

2. Insert the bezel arms into the rectangular openings on top of the mounting body.
   If your printer makes poor external dimensions, you may have to sand the tabs down a bit to make them go in all the way. This part has intentionally tight tolerances to ensure the mount can't wiggle free and drop the ET5.

3. Thread 2 screws through their own washer, and insert them through the screw holes from the front of the mounting body.
   Make sure the opening in the bezel arm tabs allign properly!

4. Insert the 4 nuts into the slots in both back arms.
   I've included small tabs to prevent the bolts from sliding out during assembly, so some force may be needed to push them all the way in.

5. Secure the back arms to the mounting body.
   Don't tighten the screws all the way yet, as it may make actually attaching the mount to the monitor become difficult.

6. Insert the two last screws through the back arms, from the bottom. 

7. Push the screw caps into the opening on the opposite side of the screws we just inserted.
   The screw caps just sit loose on top of the screw, and is just meant to protect the monitor from bare metal when tightening the clamping screws.

8. Firmly attach the magnetic mounting plate (2 loose plates come with the ET5) in the designated slot.
   Try and get it as in the middle as possible. The slot outline is just a visual reference to aid in this, but this may become hard to see on poorly calibrated printers or oozing filaments.

Mounting Instructions

1. Hook the rear arms onto the "shelf" on the rear of the monitor.

2. Tilt the front upwards so the bezel arms hook onto the bezel.
   Depending on how much you have tightened the front screws, you may have to bend the bezel arms somewhat for them to clear the bezel and click in place.

3. Tighten the 2 front screws all the way.
   Feel free to use some force here, as these screws should be very tight to ensure the mount can't flex.

4. Tighten the 2 bottom screws until they touch the bottom of the monitor.
   These help clamp the mount onto the bottom of the monitor, to prevent the mount from tilting upwards/downwards, ensuring a reliable mount.
   Do not overtighten, as that may cause the bezel hooks to pop off of the bezel.

5. Snap on the ET5, and clip the cable into one or both of the cable holders at the rear of the back arms.
