MECCANIXITY Copper Heatsink 6x6x4mm with Self Adhesive for IC Chipset Cooler Pack of 5

Exactly what I needed

After setting up a Prusa Enclosure for my printer (Which works VERY well, I will add...) I found that my printer would sometimes shift layers in both the X and Y axis. I did some searching and found a lot of claims that the Stepper Control Chips were likely getting hot from being in the enclosure and printing at hotter temps (PETG at about 250 for some super strong layer adhesion.)I planned to print some ducting to go with a fan, but that would entail designing, printing, testing for fit, wiring the fan, etc. These seemed like a quick and easy solution instead. The fit well. I tilted the printer on it's back a bit, moved some wires to expose the chips, and using a VERY small amount of thermal adhesive (I purchased something separate that is more like silicone caulk, rather than using the adhesive pads sold in this kit...), I stuck the heatsinks on. After a few hours I tilted it back up on it's feet and let it sit overnight.It's printing fine. I haven't REALLY tested for temps, but so far no layer shifting and it's printing as good as usual.

Works great

Need to cool some switching regulators (with help of fan). Worked well.Added red rtv to secure in place since they were mounted vertically. Would not trust the adhesive over time unless maybe horizontal.

made of real copper. base is a bit uneven so I had to lap it a bit so the adhesive pads get even coverage. Adhesive thermal pads needs to be cut to size too. other than these minor gripes, the heatsink worked well for my purposes.

Smart Tool board EBB36 needed a heat sink for the 6x6mm chip. They supplied an oversize one that ended up in the way. I choose these and used the supplied heat sink on the larger chip and this on the smaller chip. Worked very well and looks like it belongs there. I will use these on other devices as well.
