Spool lamp

Spool Lamp – A Creative Upcycle Project

The moment I got my hands on a 300mm LED strip and noticed the holes in a Bambu reusable spool, inspiration struck—I had to turn it into a lamp!

The concept was simple: use the spool as the core structure to hold everything together. The result? A sleek, modern lamp with a warm, cozy ambiance, enhanced by the subtle glow escaping through the tiny holes on top.

If you have an empty Bambu reusable spool lying around, why not give it a try? It’s a fun and rewarding DIY project!

Printing Instructions

Material:

I used white PETG, but PLA and other materials should work just as well.

Print Settings:

Layer Height: 0.2mm (standard)
Infill: 10% gyroid for all parts except the lampshade
Lampshade: Printed in vase mode with 3 bottom layers

Required Extra Hardware

The only additional components you’ll need are the electronics, all available from the Bambu Maker Supply Market. Here’s what to get:

Item	Price (€)	Quantity	Total (€)
COB LED Strip Light - KA009	7.24€	2	14.48€
Maker's Supply Electronics Bundle - ZH038	10.33€	1	10.33€
Total price			24.81€

Assembly instructions :

Let me know if it worked for you in the comments :)

Connect each long wire to the 300mm LED strip.
Use the short wire to connect the potentiometer to the "SW0" port on the distribution board.
Insert one jumper cable into "SW1" and the other into "SW4" on the distribution board
Place each LED into its dedicated groove in the Base.
Secure them with tape to make assembly easier.
Place the bottom part of the Bambu reusable spool on top of the Base, making sure each LED passes through the holes.
Ensure that no LED strip or wires get pinched between the Base and the Spool—they should sit flush.
Carefully pass the two wires through the two holes in the Spool Core. Tip: Guide the wires with one finger while placing the Spool Core with the other hand.
Ensure the wires align with the LED strips.
When in place, it should look like this
Flip the Assembly: Hold the Spool Core with one finger to keep it in place. Firmly grip the Base and Spool and flip the entire assembly.
Insert the Base Screw by hand.
Tighten it using the printed tool (avoid over-tightening to prevent breakage).
Pass the USB power cable through the Base Screw and Spool Core.
Plug the USB power cable into the "IN" port on the distribution board (opposite the potentiometer).
Insert the Distribution board into its groove until it clicks into place.
Connect the LED Wires: Attach both LED wires to the "CH1" and "CH4" ports (opposite the jumper cables). Tip: Use pliers to insert them carefully, ensuring the correct orientation before pushing them in.
When installed, it should look like this :
Then install the potentiometer, making sure the wire is not pinched
Screw in the Potentiometer Screw to hold it in place.
Ensure it sits flush and straight.
Place the Lampshade on top of the Spool, aligning the LEDs through the holes.
Install the LED Track: Position the LED Track and start pressing the LED strip into the groove. Tip: Begin at the tip (LED facing up) for an even light distribution.
When assembled it should look like this :
Leave a gentle curve at the base of the LED strip to prevent damage.
Lock the top part of the Spool in place securely.
Push the Knob onto the potentiometer until it is fully seated.
Plug the USB cable into a phone charger and light it up !
I made an alternate Lampshade if you prefer the wavy pattern
Use the Knob to adjust the brightness and enjoy :)
