I didn't liked most of the models for the manta kit, as they first take a lot of filament and second mostly don't fit my Prusa Mini. Also there was not really a model for the Essential Kit.
As all iFixit hard shells (Essential, Manta and Mako) only differences is in height and width, I designed a 2 part model and changed the hook position to compensate for the different kits width.
Print with support for the hooks.
Added an open Manta version, so you can mount it without the lid and access everything, while mounted.
The Essential Mount was somehow not working as expected, seems like I meassured wrong. I uploaded a new v2 version, it is not perfect but works.
The author marked this model as their own original creation.
