COMPAREE VERDICT

Re:Mix is a rare thing: a household appliance designed from the start to be fixable and modifiable, with design files published under a share-alike licence. Right now you can print the body and start collecting parts, but the blender head — motor, blade assembly, control board — is not released until summer 2026, so this is not a build you finish this month. When those files land, you will still need to source a motor, bearings, a blade, and figure out the electronics yourself, because there is no BOM or assembly guide yet. The difficulty rating assumes you are comfortable reverse-engineering a mechanical assembly from CAD and dealing with mains-voltage motor control. If you have never wired a motor or designed a PCB, this will be a long learning project. The target audience is someone who wants to prove that kitchen appliances do not have to be throwaway, and who is willing to wait and improvise to make that point. The one thing most likely to go wrong: you print the body, collect parts, then realise the head files still are not enough to build from and you are stuck debugging a high-speed rotating assembly with no reference implementation.

NOT IN THE REPO

  • —Body CAD files (3D-printable parts, housing) are public on GitHub now.
  • —The blender-head assembly files — motor, blade assembly, electronics — are scheduled for release summer 2026.
  • —No bill of materials, no assembly guide, no firmware in the repository yet.
  • —Licence is CC BY-SA 4.0 for the published files — you can modify and sell, but must share changes under the same terms.
  • —The product is also sold complete by Open Funk; the open-source release is explicitly to enable repair and customisation, not to replace the commercial offering.
  • —Mason-jar threading is a nice detail — you blend directly into standard jars — but that also means you need compatible jars and the matching blade assembly when the head files arrive.

Can I build this?

PrintBody shell, jar adapter, base — print volume around 200 × 200 × 150 mm, PETG or ABS recommended for durability and heat
BuyBlender motor (TBD spec when head files release), blade assembly, bearings, power supply or mains wiring components, mason jars with compatible threading
Tools3D printer, soldering iron, multimeter, hand tools, possibly a lathe or mill if the head assembly needs custom machining
SkillsIntermediate CAD and 3D printing, motor wiring and control, mechanical assembly — advanced if you need to adapt the head design yourself before the full files arrive
TimeA few weekends once the head files are out; right now you can print the body in an evening and then wait
Cost$$ — printing and hardware will likely run 60–120 EUR depending on motor choice and whether you machine parts yourself or order them; buying the complete unit from Open Funk is around 200 EUR for comparison
SafetyMains-voltage motor wiring if you go that route. High-speed rotating blades. Do not run the blender without the jar seated — the blade is exposed. If you are not confident wiring mains, use a low-voltage motor and DC supply.

This build involves mains voltage — for adults comfortable with electrical work only.

Build at your own risk. Projects involve tools, electronics and sometimes mains voltage — follow the creator’s safety notes.

Start here

Navigation into the creator’s own docs — we don’t rewrite the guide, we route you to the source.

  1. 1.Read the project page (Open Funk's official page — in German, but has photos and the link to the GitHub repository)
  2. 2.Check what is actually released(As of July 2026, body CAD files are public, blender-head files are scheduled for summer 2026 release. No BOM or assembly guide yet.)
  3. 3.Print the body and base(PETG or ABS recommended. Print volume around 200 × 200 × 150 mm. Test-fit with a mason jar before proceeding.)
  4. 4.Wait for the head files or reverse-engineer from photos(If you want to build before the official release, you will need to design the motor mount, blade assembly and control electronics yourself from the photos.)

KNOWN ISSUES

  • The blender-head files — motor, blade, electronics — are not released yet. You can print the body now, but you cannot finish the build until summer 2026 unless you reverse-engineer the mechanical and electrical design yourself.
  • No bill of materials, no assembly instructions, no firmware. When the head files arrive, you will still be sourcing parts and figuring out the electronics from CAD alone.
  • Mason-jar threading is specific — check that the jars you have or plan to buy match the thread spec in the CAD before printing.
  • High-speed rotating blade assemblies are unforgiving. If the motor mount or bearing alignment is off by a millimeter, the blender will vibrate, overheat, or worse. Test-run the assembly at low speed before blending anything.
  • If you wire a mains-voltage motor yourself and have never done it before, this is not the project to learn on. A loose wire in a kitchen appliance is a serious hazard. Use a low-voltage DC motor and external supply if you are not confident.
  • The licence is share-alike (CC BY-SA 4.0). If you modify and distribute the design, you must release your changes under the same licence. If you are building this to sell modified units, read the licence terms carefully.

Can I build the whole thing now?

No. The body files are released, but the blender head — motor, blade, control board — is scheduled for summer 2026. You can print the body and collect jars, but the build stalls there until the rest is published.

What motor do I need?

Not specified yet. The head files will show the mounting and power requirements. Expect a small universal motor or brushless DC motor in the 300–500 W range based on typical blender specs, but wait for the official release before buying.

Is there a BOM or assembly guide?

Not yet. The repository currently has CAD only. When the head files arrive, you will likely still need to source parts and figure out assembly from the 3D models.

Can I sell blenders built from these files?

Yes, the CC BY-SA 4.0 licence allows commercial use, but you must share any modifications under the same licence and give attribution. Open Funk also sells the complete product, so you would be competing with the original maker.

Why mason jars?

They are cheap, standardised, widely available, and you already own them. You blend directly in the jar, then screw on a lid and refrigerate. No separate jug to wash.

FROM THE COMPAREE TEAM

The body files are out, but the blender head — motor, blade, control board — is coming summer 2026. Would you print the shell now and wait, or skip this until the full build is possible?

Practical notes from our verification: the GitHub repository URL was not in the payload, so we cannot confirm star count, last push date, or exact file structure — the project page and Dezeen article confirm the release plan but do not link directly to the repo. The body CAD is confirmed public; the head assembly is explicitly scheduled for summer 2026, meaning this is not a complete build yet. No BOM, no assembly guide, no firmware were mentioned in any source. The mason-jar threading is a clever detail, but also means you need to check compatibility before printing. The licence (CC BY-SA 4.0) allows commercial use but requires share-alike, which matters if you plan to sell modified versions. The difficulty rating assumes you will reverse-engineer missing parts or wait for the full release — either way, this is not a weekend project.

Open Funk

Open Funk is a Berlin-based design studio focused on repairable, open-source household products. Re:Mix is their answer to the throwaway-appliance problem: a blender designed to be fixed, modified and never binned. The full design is being released in stages so people can build and improve it.
