What's in the pack

  • STL of every part, already in print orientation (digital edition with a small cut-in HW mark)
  • STEP of every part, for remixing
  • Bambu Studio 3MF plates for the A1 (0.4 mm nozzle): PLA, 0.20 mm, no supports
  • Illustrated guide (PDF) with real photos of our prints: print settings, the Twist Key, mounting, troubleshooting, care
  • Material Guide (PDF): PLA vs PETG vs PCTG, colours and brands, grams and time per part, fit tolerances
  • Bill of materials (CSV + PDF), README, LICENSE, CHANGELOG

Mounting

  1. Hold the mount on the board with each socket over a SKÅDIS slot.
  2. Push a Twist Key, wings vertical, through the socket and the slot behind it.
  3. Turn it a quarter turn counter-clockwise until it stops. The bar locks behind the board and the shoulder wedges the mount tight.
  4. Drop cells in at the top. Take the one in the cradle (lift it over the lip at the notch) and the next rolls in. 9V blocks lie flat and pull out through the finger notch.
03 / Print notes
  1. Print at 100 % in millimetres with X-Y hole and contour compensation at 0. Every part is already in print orientation: no supports.
  2. PLA is what we print and photograph. PETG and PCTG should work but are not tested by us (see the Material Guide).
  3. Print one Twist Key first (11 minutes) and try it on your board before the big parts.
  4. Turn on elephant-foot compensation: a flared first layer is the usual reason a key or device feels tight.
  5. Clean any stringing or seam blobs inside the columns so cells roll freely.
04 / Honest status

What we verified.

Verified = shown by our own prints and photos, October 2026. Everything else is calculated from CAD and published sizes.

Verified with our prints

  • AA dispenser printed in PLA from these files and used on our own SKÅDIS board: it holds AA cells and the next cell rolls into the cradle when you take one (photos).
  • Twist Key: printed in PLA and used on our own SKÅDIS board; it locks in snugly with a quarter turn.

Calculated / not yet printed

  • AAA and 9V dispensers: same system, sized for the IEC 60086 maximum cell sizes plus clearance, NOT printed by us yet.
  • How reliably every cell rolls out over months of use: not tested.
05 / Questions

Good questions.

Something else? Email help@harbeworks.com.

Is this a physical item?

No. It is a digital download: one ZIP with the print files and guides. Nothing is shipped. You need a 3D printer (or a print service).

Which printers does it work with?

Any FDM printer that prints PLA. The 3MF plates are set up for a Bambu Lab A1 with a 0.4 mm nozzle; on another printer use the STLs with the settings in the guide.

Do I need screws or tools?

No. Each mount hangs on IKEA SKÅDIS with our printed Twist Keys: push through, quarter turn, done.

Can I sell prints or share the files?

No: the licence is personal, non-commercial use. Please link people to this page instead. A printed version is in our Etsy shop.

What if a fit is off on my printer?

Email help@harbeworks.com with your printer, filament and a photo. The guide has a troubleshooting table, and fit tests are included where a device needs one.

Why is only the AA shown?

It is the one we printed and use. The AAA and 9V files are in the pack, labelled "not yet printed"; we will add photos when we print them.

06 / Licence

For you, with a few rules.

Personal, non-commercial use: print and use the mounts for yourself. Do not share, re-upload or sell the files or printed parts. Full text in LICENSE.txt in the ZIP.

IKEA and SKÅDIS are trademarks of Inter IKEA Systems B.V., used only to describe fit. Harbe Works is independent and not affiliated with or endorsed by IKEA.
