3D model description

Adapter for transforming CHC / TH screws or nuts into knurled handles

Available from M3 to M8

For each adapter, 2 stl files are available each time, the first one with theoretical dimensions and the second one with 0.1mm of play to allow a quick manual assembly.

Tolerances can change depending on manufacturers, printers or print settings and several adjustment tracks are possible:

  • during the modeling, the 3D being available, it is enough to change the dimension of the diameter of the head, possibly of the diameter of the stem.

  • when cutting, play with the scaling.

  • during mechanical assembly, if the play is too small, heat the screw (with a soldering iron for example) to adjust the cavity or put the screw through the hole and tighten it with a nut + washer. If the play is too high, add friction via the through hole, glue or use a nut.
