AeroPress Filter Cap Alternative

Update 25 August:

Even in the very good colorfabb filament this print failed due to poor Z axis bonding! I’m considering printing sideways with supports and annealing. Proceed carefully. Do not print in any standard filaments for use with hot water!
 

If you want a custom hole/drip pattern, let me know :)

I printed this with HT Clear from colorFabb. First day with it and I'm impressed! I tweaked the settings a lot but the final product shows zero softness or deformation from boiling temperature water (poured not submersed). I did model in almost 0.5mm diameter changes due to the tolerances I saw in this material. 

Filament settings that I used: 

• 280°C nozzle
• 100°C bed
• 12mm mm³/s vol speed
• 1.02 flow ratio 
• Cooling all layers (ie, 0 layers “no cooling”)
• Normal Z Hop

Slicer settings:

• 0.4mm for ALL line widths
• 3 walls, 5 top shells, 5 bottom shells, 75% rectilinear sparse infill
• Normal supports with 2 layers of PLA for the interface
• 10mm outer brim

Worked perfectly!

The filter cap won't work with other cap wrenches due to the removal of the deep side cuts in the original product. So I made a quick wrench with ~0.3mm offset. This should account for tolerances between different filaments but I have not tested that yet, so if you print the wrench in some other filament with different settings you may find it being too loose or too tight.
