Overview

I think we can all agree that the plus 4 needed a filter redesign and a HEPA filter added. This variation features an aesthetically pleasing design and great filtration. It works extremely well in conjunction with the 8038 Fan Mod, and would consider it a prerequisite. To fill the advanced filtration system simply lay it on its back and fill it with pellets. Make sure not to overfill, you do want a little room for the pellets to be able to situate. Then install the HEPA filter to keep them in place. See image below:

The filtration system fits extremely snug, as the rails will push in on the filter a bit on each side. To remove the filtration system from the Plus 4 put one thumb on the fingerprint and your other thumb above the HEPA filter and push up. The tight fit ensures air isn't traveling around the filtration system.

 

Bill of Materials

Activated Charcoal-Just make sure you get the longer style pellets, and you should be fine.

HEPA Filters-The filters are made for a robotic vacuum called an I-Life. The filters fit the models: V3, V3 Pro and V5.

 

Printing

Print either laying flat on its back or standing upright. I personally use tree supports on the build plate only for this model. Make sure you are using a filament that can withstand the heat of you printing. I personally recommend ASA or ABS. 

 

Nozzle: .4

Filament: ASA/ABS/PA
