A simple container and dispenser for disposable acid brushes, commonly used for spreading glue, oil, acid, flux, solder, and pipe dope on projects.

This dispenser was built for 3/8" acid brushes measuring 5.5" in length (specifically these brushes available on Amazon: https://amzn.to/3861o15). Refer to the image below for all critical dimensions (units displayed in inches).

The container will hold approximately 150 to 180 brushes. Perfect for holding and dispensing a 144 pack of brushes with some room to spare.

After printing, the container can be mounted to a wall using the integrated recessed holes for screws or using double-sided tape for a less destructive method of attachment.

Print Instructions

This is a relatively simple print but it is a long print due to the height.

Suggested settings with PLA:

• 100% infill (for this model, infill really does not make much difference)
• 0.25 mm or better layer height
• Position model upside down on the build plate
• Manually add supports just for the extreme overhang of the brush tray (see picture below for example in PrusaSlicer)
• You may want to add a brim if you have trouble keeping the model in place while printing (as pictured, printed without a brim; only a skirt)

This image shows manual supports added just to help the brush tray print accurately.

As shown, printed with MatterHackers Build PLA in Forrest Green with 0.25mm layer height and 100% infill. Sliced in IdeaMaker and printed on Raise3D E2.
