EVA (V-Core and V-Minion) with brass inserts

EVA is designed as a beginner-friendly carriage system, it is based on M3-screws and regular hex nuts. Brass inserts have several advantages over hex nuts: They won't fall out, and the risk of damage from too much torque is lower, especially in ABS and ASA parts. Inserting a brass inserts requires a soldering iron, and the inserts are a bit more expensive than the nuts.

EVA 2.4.1 was just released, and I modified relevant parts to accept brass inserts. The recommended sizes are M3x4.6x4 and M3x5x4. Don't use M3x5.6x4, as some holes are close to edges.

This repository contains 19 parts from EVA and two parts from the 5015 dual fan mod from Supersniffles.

I recommend to use these parts and complete your build with the parts from the regular EVA repository. The bottom part, for example, has no nut pockets so I did not modify it. The same is true for the probe mounts. You get these from the regular EVA 2.4-repository on github.

The "core" of EVA consists of: 

• Universal face: Use from this contrib. Don't use the regular one, or support parts will get you into trouble.
• Top plate (holds the extruder): For Orbiter and Sherpa, use this contrib. For others use the regular parts. If I did not modify an extruder plate, then it simply has no nutpockets. 
• Bottom plate: Use from this contrib. There is a standard bottom and one for the dual-5015 blower back.
• Back plate (core-xy or cartesian): Use from this contrib - standard, dual-5015 or cartesian
• Hotend-face and the matching support-part
• Fan ducts: These depend on the backplate. I clustered them into the carriage parts, together with the back plates.

Probe mounts: Use the regular ones. They have no nut pockets.

Shrouds: Use the regular parts. No nut pockets either.
