Wild Dagger 2S Battery section

This is still a work in progress, working up a complete model for a modular chassis for the Wild Dagger/Double Blaze/DualHunter etc. This was roughly based on the original design, stretches the chassis a hair over an inch to accommodate 2X 2S batteries, as well as (Most importantly) being able to fit my Vaterra Suburban body.
Happy to hear any feedback - this is really my first 3D modelling attempt so I've learned as I go, some of the earlier work in this model is a bit messy so if anyone wants to try and improve please do, but also please link back to the original and communicate back to me so I can learn from it too!
This is the most current version as of 4/16/23, most recent change was to trim a little from the chassis rail mounting section to account for a minor misalignment.
