AAA Mechanical Battery Dispenser Slide

A dispenser for your AAA batteries.

Will hold up to 35 batteries.

Model consists of multiple print plates, some for 0.2mm layer height and some for 0.16mm layer height.

All 0.16mm layer height plates needs to printed.

The Main parts (0.2mm) profile is divided into 3 options:

• One color print. ~4h 56m
• Duo color. (Plain front cover, AAA text) ~5h
• Decorated. (optional 3-4 color print) ~5h 8m
  • Separate plate for the dino (2 color). ~33m

The 0.16mm profile has two plates, both print by object:

• Guide rail and spring lever. ~58m
• Leveling knobs. ~31m

For better quality the slide may also be printed at 0.16mm layer height.

Disclaimer:

There is a requirement for the function of the dispenser that the moving parts are friction free.

There may or may not be need for minor adjustments to ensure smooth operation.

This print may not be for you if you do not desire any post processing.

That being said, adjustments should be minor and quite obvious. There is only one mandatory adjustment needed.

As a start, inspect all printed parts and remove any zits, blobs and stringing.

All my test prints are done with eSun PLA+ on a X1C.

Tools needed:

• Flat head screwdriver (4mm)
• Knife

Preparations:

1. A small slot in the main casing needs to be made straight, if not already. Du to the surrounding details this detail often come out a bit curved. I debated whether or not to design my way around this, but decided not to as the fix is easy.. Cut so that the walls are straight. Make sure to remove any debris from the void.

1. Trial fit the actuator in the grooves on the main casing. ensure this can slide without any binds. Repeat for both sides.
   1. Sharp corners combined with over extrusion may introduce inaccurate corners. If this is the case, cut flush.

1. Do the same as in 2) for the actuator and the actuator cover. Ensure smooth sliding.
2. Repeat the check once again with the actuator and the actuator cover assembled on the casing.
3. On the slide there is an axle needing support. Cut away any excess filament from the underside of the axle from the side of the supported area. There is already a recess in the axle so it is only the sides that are important. Trial fit the spring lever and check that it is free to move. Leave the lever installed on the slide.

All preparations are now done.

Assembly:

1. Insert the pivot stoppers in the front and back casing and secure with the locking clips. The pivot stoppers on the back casing has a notch in them, make sure you install them on the correct place. The locking clips are also different and will only fit on one side.
   1. Make sure the pivots can rotate freely.

1. Assemble the leveling mechanism onto the back casing. This is the same as for the AA Mechanical Battery Dispenser, and assembly instructions is described there - point 5 and onwards.
2. Slide in the casings onto the slide. The front has a dovetail and a groove, the back a dovetail only.

1. Insert the three spacer plates. Do the top one last.
2. The actuator has a pin in the bottom, insert it in to the spring lever hole and pivot it into its groove on the casing. You need to push the lever a little while installing this.

1. Insert the actuator cover. Push the lever down for it to enter.
2. Repeat for the back casing.
3. Install the button on the lever.

When pushing the button the actuators should both come to rest at their starting position after you release.

Adjust the guide rail to fit your brand of batteries and you should be good to go 👌

The last leveling knob can be critical to get right for proper sliding down the slide.
