Timemore Sculptor 078 / 078S - Single Dose Hopper & Optional Bellows Combo - Zero Retention

For a frustration-free dosing experience, whether you slow feed or dose all at once, upgrade your Timemore Sculptor 078 or 078S with my 3D-printed single dose hopper. The most important feature it provides is an effective anti popcorn design and pairing with my optional custom silicone bellows will help you get precisely what you put into the grinder for each dose, up to 0.0g retention on each grind*, all while aesthetically matching the grinder.

After nearly a year of development 40 iterations (with amazing valuable community feedback) this latest version is refined for simplicity, performance, and seamless integration with your grinder.

The hopper for 064/S is now ready here!

Features

Reliable Anti-Popcorning. Whether you dose all at once or slow feed, the beans and fragments stay within the hopper and flow into the grinder.

Matching Aesthetics. The single dose hopper replaces the original stock hopper while maintaining its cylindrical aesthetic motifs, with a textured outer surface to match the grinder's surface.

Strongly Anchored. Simple installation uses both stock screws (not included) to securely attach to the grinder, taking just a minute or two. Also makes use of the stock silicone screw hole plugs (not included) to plug up the screw holes.

Optional Bellows. While the grinder's Rotary Knocker is already very effective at reducing retention, my custom silicone bellows can take it a step further to help bring that rentention down to 0.0g*.

Compact Design. All the critical features listed above, condensed into an optimally small form factor.

Optional Lid. Helps keep the hopper dust free, like when left for an extended period of time. Lid can cover over the bellows if there is one sitting in the hopper.

Built-in groove at the bottom of the hopper for an o-ring (not included) for an extra effective hopper seal.

Compatibility

• Timemore Sculptor 078
• Timemore Sculptor 078S
• Note: May not work with the anti-static/anti-popcorn metal piece between the hopper and the grinder, so it may need to be removed during hopper installation
• (Optional silicone bellows is 100% cross-compatible with Niche Zero and Duo and several other INTROVERT Single Dose Hoppers)
• Not compatible with Sculptor 064 series (separate listing here)

Tools Required For Installation

• Small diameter (under 6mm) phillips 1 tip screwdriver
  

Subpar Bellows Option

These bellows will have a pronounced distorted form, and possibly other surface blemishes, but they otherwise are fully functional. Although some of the openings of the bellows may look far from circular, they will conform when placed into the hopper.

*Disclaimer

• In some situations like listed below, retention may vary from 0.0g-0.2g
• Grinding after cleaning the insides of the grinder will cause more retention for a few doses
• Grinding after changing grind size may cause some retention
• Using darker roasts may cause more retention than lighter roasts
• RDT method not recommended
• Achieve the best results with lighter roasted beans and at a consistent grind size setting.
• Listing does not include the grinder, the stock hopper, nor the screws or silicone plugs in the photos
• Colour of the hopper will not 100% match the grinder due to difference in materials, but I tried my best to source the closest shade PLA
• Due to the nature of the white 3D printing material, the white hopper may appear to be translucent in some lighting situations, showing a cellular pattern inside.
• If your hopper or bellows is not working as well as you hoped, please drop me a message and I'll do my best to help out.
