OXO Rapid Brewer Leveling Palm Tamper

I created this model because I was having major issues with uneven coffee beds / pucks after brewing on the OXO. This meant that the majority of the water was flowing though one area of the coffee bed in particular, which lead to some of the grounds being over extracted, while others were under extracted. Below are some of the features that were included in this model.

Tapered Sides - Since the ORB basket is more narrow at its base, this tamper is tapered to match the basket which will make it easier to create flat even tamping.

Level Rings - The rings around the outer edge indicate if beds are level for both before and after tamping. If one side looks off, make correction by applying more pressure to the side that looks higher.

Chamfered Edge - The bottom edge is chamfered to draw water toward the center of the coffee bed, rather than the outer edge.

There are two versions available of this model, depending on preferences or intended use.

V1 - Will fit inside basket fully so ideal to store inside the basket when not in use or travelling. Ideal for smaller doses.

V2 - Ideal for larger doses (20g-23g) Will NOT sit fully inside basket. Slightly larger than V1 so that there is less wiggle room when tamping larger doses.

Slicing & Printing Tips

This model is designed to be able to print either normally or upside down without supports depending on your set up or preferences.

Benefits of upside down printing would be enabling ironing on tamping surface if desired. This may be a good option for those who have a highly textured build plate.

If printing normally, I recommend using archimedean chord infill pattern for base layer in order to have as few gaps in tamping surface as possible.

Aside from that, the only issue that may occur is the seam. I used an exacto knife to just cut mine off and it worked quite well. I used PLA with pretty standard slice / print settings.
