OXO Rapid Brewer (ORB) Modular Tamp

UPDATE 01.23.2026 - I've added an additional tamp base that allows the original tamp to slot into the bottom. This way only the original tamp touches your coffee grounds instead of the 3D print itself. This new base fits the same inside of the coffee chamber. For travel I've found that I can place the original tamp upside down in the water chamber, while the modular tamp sits in the coffee chamber.

The OXO Rapid Brewer (ORB) has quickly become a staple in my household. But as many have found, the included tamp is not a great option if you want your bed to be consistently level.

Introducing the ESB3D ORB Modular Tamp!

This version of the tamp is taller so it can hug the walls of the coffee basket to make level tamping easier. This tamp also allows the use of different handles to help you find the most comfortable fit.

The tamp's base is the main attraction. It can be used by itself if you just want a quick and simple solution and it stores nicely in the coffee basket.

Adding the tamp handles requires a bit more work (but not much), and once complete can easily be attached/removed as needed.

You'll need the following materials to attach any of the handles to the base:

2.5 MM Hex Key Allen Wrench - I use one from this set

M4x12 Screws

Materials Used: (1) M4 heated insert for the base, (1) M4 heated insert for each handle, (1) M4x12 screw for each handle.

Steps:

1. Install a heated insert into the top of the tamp base until flush.

(for PETG I set my iron to 260C)

2. Flip your chosen tamp handle upside down and install a heated insert until flush.

(The hole on top of the tamp handle is too big for the heated insert).

3. Wait 5-10 minutes for the heated inserts to cool.

4. Drop a M4x12 screw into the hole on top of the tamp handle and screw it in until it's tight.

(A bit of the screw should be coming out of the bottom).

Annd you're done! Now you can easily attach or remove your finished handle into the base.

Print Properties I used:

All Parts - PETG, 20% gyroid infill, 3 walls/perimeters

Tamp 1 - Organic "supports on build plate only". The automatic supports did a good enough job for me.

I used PETG for it's higher temperature and water resistance properties.
