CORE One+ Printhead Cover Right Lever without obstructions

I always found it annoying that one of the idler screws on the CORE One+ is obstructed by the automatic vent opening lever. With the standard Torx screwdriver, it's almost weird to reach the rear screw properly. Yes, a ball-end hex key works, but it's still an unnecessary inconvenience to grab another tool - especially since the original Torx screwdriver can be used for almost every other screw on the printer if you are careful.

During the repeated assembly and disassembly of the Nextruder while prototyping the CORE One Mini, I originally planned to modify the lever and leave the Upg Vent Block on the top cover unchanged. After a while, however, it became clear that this approach wouldn't work due to the altered travel limits and the redesigned lever geometry.

Instead, I redesigned the mating part and kept the Printhead Cover Right Lever unchanged. Then this annoying design flaw reminded me of itself once again, so I decided to redesign the lever as well. The result is a new lever that is compatible with both the CORE One+ and the CORE One Mini while eliminating the obstructed idler screw, making Nextruder maintenance or changing tension for flexibles much more convenient.
