Description
This compact Filament Respooler incorporates a stepper motor and a filament runout sensor for ease of use. You can also use the app to fine-tune the settings and monitor the progress. In my experience, it works great! The Respooler is optimized for the Bambu Lab reusable spools and compatibility with other manufacturers is not guaranteed.
Improved Respooler Pro now available here!

Needed Hardware and Electronics:
- The Respooler uses an ESP32 to control all the functions
- Most of the needed parts can be ordered via Bambu Lab's Maker's Supply, just use the âBUY NOWâ button at the bottom of this page
- To connect the ESP32 with the rest of the electronics, there is a custom PCB available via my Store or you can order your own from the provided Gerber files. There is also a shared project on PCBWay.
- Flash the needed code to the ESP32 using the Web Flasher
Please check for the availability of the PCBs first before printing or purchasing the other parts!Â
đ All the code, Gerber files along with the print profiles for previous versions are on GitHub.
There is an iOS App to configure and control the Respooler! Android users can use the Web version for now. The app is optional! The Respooler still works completely fine without it. I made it mostly for fun and to learn app development. Get it here:
How to use it:
- Feed the filament from the top spool through the PTFE tube
- The LED will turn green. Without filament, the motor does not start
- Attach the filament to the bottom spool (I recommend this model) and press the button
- Once all the Filament has been transferred, the motor will automatically stop
- If you want to pause the winding, just press the button again
