General tips

❗️ Important!

Use STL (not STEP) files for Slic3r forks, i.e. Prusa-, Orca-, Bambu Slicer. STEPs are for CADs. There has been many cases reported when a STEP file has caused invalid geometry, including critical changes such as "no gap between button and shell".

Printing

1. There MUST be no supports, unless you really know what you are doing.

2. PLA, PETG, ABS — any of those are fine.

Other

1. Insert magnets on a flat hard surface while the device is not assembled.

2. Cyanoacrylate (superglue) works nice for magnets.

3. If you experience buttons sticking, try loosening the screws or removing the sensor cover.

4. If you experience bad tracking, you may want to print and install spacers.

57-68 mm ball (or 50-60 mm with spacers installed)

50-55 mm ball

Also available for non-standard BTUs: SP-8, Veichu-15.

If you use CY-8H Aliexpress BTUs, it is recommended to go with the 50-52.4mm version instead.
You can ignore the fact that it is deprecated in such a case.
That version (in combination with this BTUs) should work with a 55 mm ball too.

50-55 mm ball (short version)

Fits a 50-55 mm ball. In this mod, the bottom and top parts of the original Adept case have been modified.

50-55mm ball (short, thin bezel)

Fits a 50-55 mm ball. In this mod, the bottom and top parts of the original Adept case have been modified.
It was built based on the short version above.

44-45 mm ball

This mod fits the original 45mm ball.
You can find the 3MF files for Bambu printers on Makerworld.

50-52.4 mm ball DEPRECATED

The shell is deprecated, see 50-55mm one. It has standard size buttons and better BTUs placement.

BTUs needed

This is the link to genuine BOSCH Rexroth BTUs.

CY-8H BTUs from AliExpress are compatible, with one exception so far.
SP-8 and Veichu-15 are not directly compatible, but there are model(s) available.
Rexroth BTUs are clearly superior and are highly recommended.

Magnets

You will need 4x2 mm circular neodymium magnets, full set (device + buttons) is 24pcs.
They MUST be glued, ideally with a cyanocrylate based glue.
