What If I Don't Have A 3D Printer?

Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.

3D Printed Retainer

The carbon filter retainer is designed to be 3D printed with FDM type 3D printers.  To 3D print the part, we used a 0.8mm nozzle which allows for printing a bigger layer height and extrusion width.

  • 0.8mm uses more material but reduces total print time.
  • 1hr 30min to 3D print (4 hours with0.4mm nozzle)

Ultimaker Print Cores

The Ultimaker 3 features swappable Print Cores that are designed for fast nozzle changes. The all-in-one design contains the heater block, sensors and nozzle all in one package. This makes maintenance low and speeds up  prototyping workflow. The AA 0.8mm print core is designed to push out more material allowing for thick layer heights and line widths.

Slicing The Part

This part has lots of overhanging features and retraction movements. Reducing the print speed and increasing the active cooling fan makes it possible to print without any supports. 

  • Use wide brim on first layer for better bed adhesion.
  • Fully cool down heated glass to remove part.

Slice Settings

These settings are for a 0.8mm nozzle profile using CURA 3.2. Optimized for the Ultimaker 2, 2+ and 3.

  • Layer Height 0.4mm
  • Line Width 0.75mm
  • Print Speed 45mm/s 
  • Retraction
    • Maximum Retraction Count - 10
  • Build plate adhesion type – Brim 
    • Brim Line Count – 8

Print Quality

The bridging on the top features are impressive, there’s a bit of sagging but it's really not bad. The grill mesh did not need any cleanup and it feels slightly springy. The print quality is quite impressive for an object with a large layer height and extrusion width.

Design Source Files

The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.
