Toner refill funnel

I needed a funnel to use for refilling my toner cartridges. It needs to fit my workcentre 3225 and 3025 toners and also the brother TNB023 cartridge which has a narrower fill port so I made this 2-in-1 funnel. 

This is designed to be printed in spiral vase mode. It can be printed with a 0.4 nozzle but the outer wall size should be 0.8 (or 200%) to ensure it's solid enough. Adjust as you see fit for larger nozzles.

The print settings I used:

• nozzle: 0.4
• spiral vase mode
• smooth spiral
• outer wall: 200%
• bottom shell layers: 0
• brim type: outer brim (just for some extra adhesion)
• brim width: 0.5
