Ender 5 (Pro) Electronics Box Replacement Lid with 120mm fan and 10mm more space

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4774618.

Important note: This design is intended to be used with the electronics box relocated to the back of the printer. Will not work on the bottom as there will be no room for air intake, let alone a fan. Update Apr 1, 2021

Added a version of the left part without the PSU guard for airflow to the PSU, in case you want to remove the PSU fan and use a mesh lid; https://www.thingiverse.com/thing:4800781

Update Jan 26, 2021

Added a version of all 4 lid-halves with flush bolts

Back-story

Inspired by https://www.thingiverse.com/thing:4203653 (which I cannot select as source for Remix, but I will keep trying) and xeroxed from https://www.thingiverse.com/thing:4636181, but fully rebuilt from scratch. This is a continuation of my previous replacement lid; https://www.thingiverse.com/thing:4761348

Description

This is a three-part lid for the Ender 5 and Ender 5 Pro (as I have been told) electronics enclosure. My goal was to create a perfectly snug fitting lid, in as little as possible parts.

Required hardware;

4x m3x16 or longer bolt for the corners, could do with M3x14 in case of the flush bolts version 3x m3x12 bolt with nut for coupling the two pieces. 4x m3x??? bolt with nuts for mounting the fan you wish.

Fan mounting

I myself mounted the fan (12 mm thick) with 4x m3x18 bolts, 4x m3x6 panel mount and 4 nuts (in order: bolt, lid, fan, panel mount, fan guard, nut) See photo for a close-up :)

Partlist

There are 10 parts in this thing 2 left-side lids, one with a fan hole 120mm and one with a simple grill and a variant of each with flush bolts 2 right-side lids, again, one with a fan hole 120mm and one with a simple grill and a variant of each with flush bolts 2 fan grills, one is flush (in case you create spacing yourself like I did, see photo) and one with 1mm spacing where the fan-blades spin.

Note

I would advise against using the simple grill version on the left side, unless you plan to use a custom fan solution that pulls air across the controller board, but for symmetry, I just had to include it (OCD!)

About the left side

The left-side part with fan hole has a cut-out for cables, as I am using a RasPi with camera. Upon request I will create a version without a cut-out, but it's easily remixed by yourself. This part also has a small airflow guard to prevent the 120mm fan from pushing air through the PSU fan, which (as I am told) is bad for a fan. (A fan should always only rotate under their own power. it's a long-term-thing)

Part height

Total "height" for printing is 14mm, the lid itself is 13.3mm (because the corners are not flush, but counter-sunk in the case). As the main-lid-area is 2.3 mm thick (because, the original was). this gives 11mm extra space. But the lid is slightly recessed, (by 1mm) so the actual space gain is 10mm.

About the fan guard

The fan guard is specially crafted for 0.2 layer height, 0.4 nozzle. (0.10 layer height would work too) it will print diagonal lines top left to bottom right on the odd layers and top right to bottom left on the even layers (or vice versa). This saves time and filament.
