WARNING

This model is for makers only! You have to use a soldering iron and might need to adjust the model in Bambu Studio to fit your electrical components. It is not print & play!

Sometimes all you need it a shining bucket in the dark.

This is an ambient bucket lamp. It uses a short LED strip and will run on 5V USB power.
Besides the printed part you need:

• USB-C breakout-board
• red & black isolated wire
• 5V LED strip (recommended: 20LEDs or 330mm of a 60 LEDs/m strip)
• on/off switch
• optional: 3x 5.5V, 1.5F, type-C supercapacitors (e.g. from Panasonic)
• soldering iron
• glue (e.g. hot glue)

The print itself is very easy: Print the bucket in vase mode with a line thickness of 0.99mm for a 0.4mm nozzle. The rest can be printed normaly with 3 walls and no support. I recommend you use a brim on the clamps and the shaft to optimize bed adhesion.

For assembly just clip the clamp on the bucket and glue them in place. Then you can install the handle. If you do not like the handle, just throw the handle and the clamps away. The bucket will shine without them.

Now comes the tricky part: Installing the electrics
Cut your 5V LED strip to 20 LEDs. For a LED strip with 60 LEDs per meter the cut part will be 330mm long.
Solder the wires to the LED strip and mind the polarity (red is +).

Put the wires through the top hole on the shaft. The wires must come out on the threaded end of the shaft. Now wind the LED strip around the shaft until it reaches the slots. Stick the end of the LED strip in one slot and secure it with glue.

Screw the shaft on the stand.
Install the switch and glue the USB breakout board in place.

The following step is optional - the supercaps will act like a short-time battery. But you can of course solder the LED strip directly to the switch and USB breakout board if you do not need or want the capacitors.
Glue three supercapacitors to the bottom of the stand. I recommend that the negative port is always facing to the middle. Connect the supercaps in parallel to the USB board and the LED strip.

Watch the polarity! Shit will happen if you mix up plus and minus! Do not say I have not warned you!
Here is the electrical layout:

Place the bucket on top of the shaft and plug-in a 5V USB-C power source. When you flip the switch the bucket should shine. If not, you made a mistake. Remove the USB power and check everything again.

When connecting a 5V power source the supercaps will charge. A full charge will take 90s. Yes - only 90 seconds. If you remove the power source the bucket will still shine for about 10 minutes and slowly fade out. This makes the bucket lamp a perfect snooze lamp.
