Print:

Important! Choose a stiff filament that doesn't bind or bend easily. Tested to work best with PLA Metal and PLA Basic. PLA Matte and PETG-HF work OK, but buttons need more loosening before assembly. PLA Silk and other cosmetic filaments are not recommended. Colors are also known to cause differences in print accuracy and part stiffness. Experiment with different materials if at first you don't succeed.

 

Use the provided profiles. If printing via Bambu Handy app, don't increase the number of copies. This can cause the buttons to move outside the housing, making the assembly impossible. If you must print multiple copies, or the buttons don't print inside the housing for some other reason, use the “MERGED” profile. The reason for this is that the buttons are not merged to a single assembly with the main body in the default profile. This is done so because it allows for the buttons to have different layer height than the body, which reduces friction between the parts. The “MERGED” profile does not have this feature.

 

The design uses small tolerances and assumes your printer functions with normal accuracy (test prints were done with a fairly new A1 mini). Check your filament calibration and printer axis & belt tension if the print-in-place parts stick together.

 

If slicing yourself:

a) Use the provided STL (not 3MF) file to make sure all parts are positioned correctly. The Buttons/Pins are print-in-place and cannot be installed if printed separately.

b) If possible, print the Body and Buttons and different layer heights to reduce binding. I used 0.2mm and 0.15mm.

c) Print the middle lever with high infill. (~100%)

 

 

Assembly:

Make sure the Buttons/Pins move freely before assembly! Move them up and down until they move smoothly and click up and down with low force.

1. Once the pins move freely and smoothly, push all the pins up and position the first end of the lever inside.
2. Push the second end of the lever inside. Some force is needed as well as finding the correct alignment.
3. Push the first two buttons down with the lever ends. Position the two ends of the lever in the lower button grooves to get more space for next step.
4. Make sure the last button is still in the up position. Push the last end of the lever in.
5. Once the lever is in, push the third button down.
6. Combine the two halves.
7. Done! If the buttons don't at first return easily, help them a bit to loosen the mechanism. Once running smoothly, the mechanism gets even better with use.
