EG4 18kv vertical fan holder

I read about some potential overheat issue for the eg4 18kv inverter, and some user suggests using external fan to help fight the heat, which leads to this setup. 

In my install, there were not a lot of room on top of inverter so I opt to create this model that points the exhaust air forward. This might help some outdoor setup that need to worry about rain or snow. 

========= Non printed parts =========

4x 120mm fan with speed controller: https://www.amazon.com/dp/B08XQJXLN8

m3 bolts, nuts and threaded inserts: 6x bolt, 4x nut, 2x insert

======== Print instruction =========

The inverter can heat up to 75~80c, and filament that have lower heat tolerance like PLA or PETG should be avoided. Suggest to use ABS or ASA for this print for longevity 

The cut model should fit in 256x256 bed in the set orientation ( I use Bambu X1 ) 

If you need to fit this on different sized bed, please cut your own using the full size model 

========= Assembly ==========

The 3 pieces of fan holder body have holes for 4 set of m3 bolts and nuts. Use the bolt and nut to connnect the 3 piece into one big piece 

Connect the side plate to either side of the 4x120mm fan, insert the m3 threaded insert to the side of the body, and bolt the fan onto the body. 

Place on top of the inverter. Gravity should keep the holder in place already, but you can use double sided tape to ensure it don't get knock off too easy. One easy way to tape this is to place double-side tapes to the 3 tabs that will extend down to the rear of the inverter, and use that portion to stick the fan holder to the inverter.
