I tried this solution by FarO and can confirm that two **3M 5516-10** thermal pads serve this purpose perfectly. Thanks!

<p>opposed to what the title of this question might impose, I'm not new to 3d printing itself and have operated more than one printer for years, however, I feel dumb with installing the Thermistor on this new Heated Bed I got from RepRap.me: <a href="https://www.reprap.me/aluminum-heatbed-mk3-400x300.html" rel="nofollow noreferrer">Aluminum Heatbed MK3 400x300</a></p>

<p>The old Mk2b 214x214 Mendel/Prusa heated bed that I have been using for quite a while now has a through-hole in the center, where the thermistor-leads could be fed to from below.</p>

<p>On this new heated bed however, there is a lowering in the very center of the Heated Bed to place the Thermistor in, yet the pads to connect the thermistor leads to right beside it are level with the rest of the Heated bed.</p>

<p>I tried using just a tiny amount of SMD solderpaste and just soldering the thermistor leads as flat as possible to the pads, nevertheless, the glass plate on top is not laying flat and stable on the heated bed with the thermistor installed.</p>

<p>Any suggestions are greatly appreciated on how improve the thermistor-installation onto this heated bed!</p>

Contact the manufacturer and complain, maybe they improve the design or at least refund you.

How is a Thermistor supposed to be installed between Heated Bed and the Glass?
