BIQU B1 Mod BMG + E3D + Fan 5015 (Maintains PCB)

This mod was specially designed for the BIQU B1, allowing various components to be mounted easily and without losing compatibility with the original hotend PCB.
With this mount, you can adapt:

• BMG or Bondtech Extruder
• E3D Hotend
• 5015 Blower Fan

The design maintains the use of the BIQU B1 hotend PCB board, avoiding electrical modifications and preserving the original electronics.

It's an ideal upgrade if you want to increase extrusion capacity, improve the cooling system, and expand compatibility with better-performing hotends.

Main Features

• Compatible with BMG and Bondtech extruders.
• Supports E3D type hotends.
• Integrated mount for 5015 blower fan.
• Maintains the original hotend PCB without the need for electrical adaptations.
• Robust design intended for long-duration prints.
• includes inductive sensor holder

Printing Instructions

• Orient the parts according to the recommended view in the files.
• PETG or ABS material is suggested for greater heat resistance.
• Layer Height: 0.2 mm (recommended).
• Infill: 30% – 40%.
• Supports: only in necessary areas.

Assembly

1. Remove the original extruder/hotend mount on the BIQU B1.
2. Install the new mod with M3 screws.
3. Mount the BMG or Bondtech extruder.
4. Place the E3D hotend.
5. Install the 5015 blower fan in its mount.
6. Reconnect the original hotend PCB.

Notes

• Verify the correct orientation of the 5015 fan for optimal airflow.
• This mod does not require electronic modifications, only mechanical assembly.
• Tested on BIQU B1 with stable extrusion results and improved cooling.
