Synopsis: Creates a NEMA standard stepper motor model. [Geom]
See Also: nema_mount_mask()
Usage:
- nema_stepper_motor(size, h, shaft_len, [$slop=], ...) [ATTACHMENTS];
Description:
Creates a model of a NEMA standard stepper motor.
Arguments:
| By Position | What it does |
|---|---|
size |
The NEMA standard size of the stepper motor. |
h |
Length of motor body. Default: 24mm |
shaft_len |
Length of shaft protruding out the top of the stepper motor. Default: 20mm |
| By Name | What it does |
|---|---|
details |
If false, creates a very rough motor shape, suitable for using as a mask. Default: true |
atype |
The attachment set type to use when anchoring. Default: "body"
|
$slop |
If details is false then increase size of the model by double this amount (for use as a mask) |
anchor |
Translate so anchor point is at origin (0,0,0). See anchor. Default: TOP
|
spin |
Rotate this many degrees around the Z axis after anchor. See spin. Default: 0
|
orient |
Vector to rotate top towards, after spin. See orient. Default: UP
|
Anchor Types:
| Anchor Type | What it is |
|---|---|
| "shaft" | Anchor relative to the shaft. |
| "plinth" | Anchor relative to the plinth. |
| "body" | Anchor relative to the motor body. |
| "screws" | Anchor relative to the screw hole centers. ie: TOP+RIGHT+FRONT is the center-top of the front-right screwhole. |

Synopsis: Creates a standard NEMA mount holes mask. [Geom]
See Also: nema_stepper_motor()
Usage:
- nema_mount_mask(size, depth, l, [$slop], ...);
Description:
Creates a mask to use when making standard NEMA stepper motor mounts.
Arguments:
| By Position | What it does |
|---|---|
size |
The standard NEMA motor size to make a mount for. |
depth |
The thickness of the mounting hole mask. Default: 5 |
l |
The length of the slots, for making an adjustable motor mount. Default: 5 |
| By Name | What it does |
|---|---|
anchor |
Translate so anchor point is at origin (0,0,0). See anchor. Default: CENTER
|
spin |
Rotate this many degrees around the Z axis after anchor. See spin. Default: 0
|
orient |
Vector to rotate top towards, after spin. See orient. Default: UP
|
$slop |
The printer-specific slop value to make parts fit just right. |
Anchor Types:
| Anchor Type | What it is |
|---|---|
| "full" | Anchor relative the full mask. |
| "screws" | Anchor relative to the screw hole centers. ie: TOP+RIGHT+FRONT is the center-top of the front-right screwhole. |
Example 1:
include <BOSL2/std.scad>
include <BOSL2/nema_steppers.scad>
nema_mount_mask(size=14, depth=5, l=5);

Synopsis: Returns dimension info for a given NEMA motor size.
See Also: nema_stepper_motor(), nema_mount_mask()
Usage:
- info = nema_motor_info(size);
Description:
Gets various dimension info for a NEMA stepper motor of a specific size. Returns a list of scalar values, containing, in order:
- MOTOR_WIDTH: The full width and length of the motor.
- PLINTH_HEIGHT: The height of the circular plinth on the face of the motor.
- PLINTH_DIAM: The diameter of the circular plinth on the face of the motor.
- SCREW_SPACING: The spacing between screwhole centers in both X and Y axes.
- SCREW_SIZE: The diameter of the screws.
- SCREW_DEPTH: The depth of the screwholes.
- SHAFT_DIAM: The diameter of the motor shaft.
Arguments:
| By Position | What it does |
|---|---|
size |
The standard NEMA motor size. |
