Upgrade your part cooling abilities! Two designs, one if you're still using insulation and Kapton blanket. It bumps into one corner just slightly. One if you're using a silicon sock like https://www.thingiverse.com/thing:2871015 or similar. Each has an option for a tiny bit of built in supports for the block with the screw hole. This design does require a longer M3 screw, I believe it was 20mm. My first version was PLA and except for the one corner getting slightly warm it worked fine. My final version printed in PET-G and has been in use for at least a year now.
