Description

Bits stand upright in rows, tip up, so you can see the size. Every hole is an ISO 1173 hexagon with 0.3 mm clearance; the bit stands on the pointed end of the hole. The rows are 20 mm apart, so you can grab each bit on its own.

  • Tile A (25 mm bits): hole 12 mm deep, the bits stand 13 mm proud; fits every height from M 112.
  • Tile B (50 mm bits): hole 18 mm deep; fits from M 137 (not in M 112).
  • 74 bits per M tile, 62 per L tile on a 13 × 20 mm grid.
  • 1/4″ hexagon bits only (form C 6.3 and E 6.3); not a holder for any particular brand's tools.

Variants and installation: Whole set (all tiles and connector bars, print profile as below): Tile set M (A + B, 2 × each) 43 h 32 min, 655 g; Tile set L (4 × A, 2 × B) 54 h 03 min, 823 g. Systainer³ M (from above, one long side at the front): front: left A (25 mm bits), right B (50 mm bits); back: left B (50 mm bits), right A (25 mm bits). The back row is the same file turned by 180°; the two R 15 corners of every tile face the case wall. Systainer³ L (from above, one long side at the front): front: left A (25 mm bits), middle B (50 mm bits), right A (25 mm bits); back: left A (25 mm bits), middle B (50 mm bits), right A (25 mm bits). The back row is the same file turned by 180°; the two R 15 corners of every tile face the case wall. Single tile: fits any of the 4 places in the Systainer³ M; R 15 corners towards the case wall, turned by 180° in the back row. Can be mixed with other tiles of the same size.

Dimensions: Inside dimensions taken from the TANOS price list 2026; our part has not been tested in the case yet. Systainer³ M: 2 × 2 tiles of 193.6 × 136.3 mm (inside 389.5 × 275 mm), 2 connector bars; Systainer³ L: 3 × 2 tiles of 166.3 × 136.4 mm (inside 501.5 × 275.2 mm), 3 connector bars. Tool dimensions according to ISO 1173. Hexagon s max. 6.35 mm plus 0.3 mm clearance = 6.65 mm. The 25 mm length is documented; 50 mm bits are common but not read from a standard (estimate). The corner radius, floor profile (floor cross, radius between floor and wall) and wall draft of the cases are not published. That is why we relieve generously: R 15 in the case corner, a 4 mm chamfer at the bottom edge, a hollow underside with a rim (a floor cross up to 5 mm high stays clear) and 1.0 mm clearance per side to the case, 0.3 mm between tiles. Print the free fit sample set first: it shows on your own case whether corner, floor edge and clearance work.

Material: PETG recommended, because a tool case quickly ends up in a car or in the sun. PLA works too, but it deforms in a hot car or in the sun.

Brands: Made to fit Systainer³/Sortainer³, not an accessory by TANOS or Festool, no affiliation with them. No logos and no lettering on the parts.

If the bits are too tight, scale the tile up by 1 % in the slicer; too loose: 1 % down.

FAQ

Which material should I use for this tool case insert?

Recommended: PETG (alternatively PLA). PETG recommended, because a tool case quickly ends up in a car or in the sun. PLA works too, but it deforms in a hot car or in the sun.

Do I receive a printed part?

No. You get the print files and print the part yourself or use a print service. You get the download link right after payment.

Have you printed the part and tested it in a case?

Not yet. Inside dimensions taken from the TANOS price list 2026; our part has not been tested in the case yet; the tool dimensions come from the standards named. That is why you should print the free fit sample set and a single tile first.

What are the connector bars for?

A flat bar (30 × 5 × 2 mm) sits in two pockets at the joint between the front and the back tile and keeps them in line without clamping. Lengthwise the case walls hold the tiles. You can also leave the bars out.

Is this an accessory by TANOS or Festool?

No. The parts are made to fit Systainer³/Sortainer³, not an accessory by TANOS or Festool, no affiliation with them. We name products only to describe the fit.

Which material?

PETG recommended, because a tool case quickly ends up in a car or in the sun. PLA works too, but it deforms in a hot car or in the sun.
