Three additional attachments I couldn't find else were that I needed for the following items:

• 58mm paper filters
• 33mm spray bottle (originally from Amazon I think)
• Fellow soft-bristled brush (came with the Ode Gen2)

Notes:

• Printed on a Qidi Q1 Pro
• 15% infill
• No brim
• Generally, default print settings should work but here are some extra details in case they help:
  • Perimeters: 2
  • Infill pattern: Grid
  • Supports?: See the notes below. 

Spray Bottle and Brush Holders

I recommend you orient as such to avoid using supports on both the spray bottle and brush holders:

If you have the ability to set variable layer width, try reducing the layer width at the bottom and top and the opening to reduce the amount of overhang material.

58mm Paper Filter Holder

I found printing this upright with supports to be the simplest solution.
