Several of the parts below are required for assembling the system; others are optional, depending on how you intend to mount the sensors, buzzers, and control unit. We recommend considering the positioning of each component before you begin printing.
You should also examine the angle of each surface on which you plan to mount a component. It can be helpful to use a small level along with the wedges below when taking these measurements.

Control Unit
You need to print each of the files below.
Note that these are relatively large, rectangular shapes. Some printers will have difficulty printing these files without producing some warping. You may want to consider using a glue stick on the print surface to enhance adhesion.

Neither file requires supports or clean-up after printing.
Proximity Sensor Enclosure
You will need to print each of these four files. Each left file is a mirror image of the right file.

All of these files can be printed without supports and don’t require any clean-up.
Buzzer Enclosure
You will need to print two copies of each of these files.

Neither file requires supports or clean-up after printing.
Jumper Wire Clips
Print (2) buzzer-wire clamps, (1) three-wire clamp, and (2) four-wire clamps.
Note that these are very small parts, and you may want to use a brim with these parts to help with bed adhesion.

Bar Mounting Clips
These clips are designed to hold tightly to round bars. Choosing a clip that is one millimeter smaller than the diameter of the bar will result in a clip that can be slid around and back and forth on the bar, but will stay in place when the walker or gait trainer is in motion. Choosing a clip that is more than 1 mm smaller than the bar diameter will hold even more rigidly but may snap when clipped into place.
Each clip can be connected to the associated component with a single screw through the center hole or, for a more rigid connection, with two screws through the two outer arcs. The arcs will allow you to make fine-angle adjustments during mounting before tightening the screws.
A 90-degree clip will hold the attached sensor, buzzer, or control unit parallel to the associated bar. If the bar itself isn’t perfectly vertical or horizontal and you’d like the device to be vertical or horizontal, you can choose an 85-degree or 80-degree version to compensate for some or all of that deviation. It can be helpful to use a small level along with the wedges below to determine which clip design to use.
| 90-degree Clips |
(one example) |
Clip inside diameter: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm |
| 85-degree Clips |
(one example) |
Clip inside diameter: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm |
| 80-degree Clips |
(one example) |
Clip inside diameter: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm |
All of these files can be printed without supports and don’t require any clean-up.
Ball Mounts
These ball mounts provide a unique way to mount the system components. The ball grip mount works in concert with either a ball mount or a ball cup mount. The grip can be rotated relatively freely around the ball to make fine adjustments to the positioning of the system component, and remains in place while the walker or gait trainer is in motion.
Normally, the ball grip mount is attached to a system component, while the ball mount, along with a ball grip mount (or the ball cup mount), is attached to the walker or gait trainer.
The ball cup mount is intended to mount to the end of an outstretched arm of a gait trainer.

| Ball Cup Mounts |
(one example) |
Cup inside diameter: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm |
All of these files can be printed without supports and don’t require any clean-up. You may want to print the ball cup mount with a brim since it has a small surface area when placed on the print bed.
Be careful when slipping the grip onto either ball. Try to keep the two prints in line as you slide the grip onto the ball and maintain equal pressure on the eight arms of the grip. Applying excessive pressure to a couple of the arms will cause them to snap. Once in place on the ball, the arms are fairly strong and resistant to snapping.
Test Wedges
These wedges, along with a small level, will help you choose the “best” mounting clip for your walker or gait trainer.
