Ender Extender 400XL Cable Chain Brackets

thingiverse

Cable chain brackets designed for the Ender Extender 400XL. (May work on other versions) This setup will require you to extend your wiring. The PM_v1.3_EZR_Struder_Front_Facing_Adapter_w_Cable_Chain_Mount is designed for the Printermods.com direct drive carriage version 1.3, Hero Me parts cooling mounts, and an EZR extruder mounted facing the front. This bracket offsets the extruder to align with the hot end and provide clearance behind the stepper to clear the Z extrusions. I have also provided the Step for this file in case you need to modify for your particular setup. The X chain bracket replaces the cover over the X stepper and utilizes that hardware for mounting. There are slots in the side of the x chain bracket that accept small zip ties to manage the cables for the X stepper and X end stop switch. The Z chain Bracket top indexes and attaches to the back of the X chain bracket. The Z chain supports provide an attachment point for the lower Z chain and also provide support to the chain. I have provided two versions. The normal one is for the 400XL with a 500mm print height. The short version is for those who may try to use this for shorter machines. All models are designed to capture the required hardware and are purposefully designed to be a friction fit to the nuts. All models are also designed to be printed with no supports. Required hardware: 4 M3x16 Bolts (Z top bracket to X Bracket) 2 M3x12 Bolts (Bracket to X Carriage) 2 M3x30 Bolts (EZR extruder to bracket) 4 M4x10 bolts (Z support bracket to extrusion) 8 M4 Countersink Bolts (Cable chains to brackets) 8 M3 Nuts 8 M4 Nuts 4 M4 T-Nuts I used these 10x15 cable chains: https://www.amazon.com/dp/B07QVKL1H6/ref=cm_sw_em_r_mt_dp_xxb4FbBHHM8DK?_encoding=UTF8&psc=1
