Hunchback Bowden Extruder

thingiverse

See how I'm going to incorporate the HunchBack Bowden Extruder into my WIP 3D printer design on Sketchfab: https://skfb.ly/LPP7. I need an extruder that meets these requirements: * Has a wider base and likely attaches to its support under the motor due to space constraints. * Uses all four bolts to secure it to the motor. * Grips the filament close to the motor to minimize stress on the bearing. * Is easy to open without unscrewing the Idler arm. * Optimizes for top-down positioning, with filament entering from below and the Bowden tube arching at 45 degrees, potentially reducing length. This design is still in progress, but posting it online allows me to gather comments and suggestions. Here are some additional details about this extruder: Printing vertically is possible, but I'm concerned about rotational forces exerted by the motor when spinning, which can cause layer delamination (I can provide a version without the back-oriented side of the foot for easier printing on the bed). There's a retaining M5 nut at the push-fit fitting with limited space, making it a tight fit (again, I can provide a version without the niche for the nut). The Idler appears heavy or massive due to supporting the bearing shaft/bolt closest to the motor, which was unsupported and prone to bending. The original extruder's Idlers broke frequently due to uneven forces, so I updated the design. The "canopy" of the idler extends towards the motor, providing a surface for the shaft support to press against when the tension bolt is tightened.
