Parametric BIQU Panda Lux A1 Holder

Intro 

This is a parametric light holder for the BIQU Panda Lux A1 LED kit.

Rebuilt from the ground up, Based on the idea by djferre here: The Cover A1 Panda Biqu Lux LED 

tldr; djferre's model is a great idea, but as mentioned in their description; not all LEDs are made equal.

Features

This version allows you to use the Customiser to change the spacing between the LEDs, the diameter, and some other variable size and positioning parameters. 

Other features/refinements to the concept that I have made:

• You can stick the lights to the part rather than your printer, to allow for easier removal and adjustment.
• The bar is thinner to increase clearance between the LEDs and the toolhead.
• The bar is longer to cover more of the LEDs.
• The bracket's bolt holes allow for some movement up and down to align the bar with the X axis gantry.
• The LED's right hand side is further away from the camera to allow for a cleaner layout of the cable.
• The LED holes are chamfered to avoid causing a horse blinders effect on the lights.

Customization Tips

The main thing to customize is the distance between each LED “led spacing mm”.

I believe the default is approximately 21mm, I found that my LEDs (purchased in the UK in 2026 from amazon) were closer to 20.8mm, so the distance of 20.82mm was right for me.

You can ballpark the difference by measuring how much smaller/larger the gap in your LEDs total, divided by the count of LEDs (14 by default).

If you're measuring for accuracy with a set of calipers, the distance is the center distance between each LED.

If there's more slop, you're not sure, or you want to experiment, increase the “led d mm” variable, that's the hole diameter for each LED, the default is about 10mm and is a loose enough fit to easily insert and remove the LEDs. Going up by a couple MM will allow you to be slightly wrong on the other variable.

The other variables included are for drastic differences (LED count), or fine tuning alignment (insets). Their description should be enough to give you an idea of how to modify them for your needs.

Parts

• 2 m3x6mm Socket head bolts. 
  • I use a set like this that includes the bolts and some washers.
• (Optional) 2 m3 washers
• (Optional) 3M tape 10mm width
  • I used this.
• (Optional) Reusable cable ties
  • I used these.

Assembly

1. Clean the old 3M tape off the part
2. Stick the LEDs to the part with fresh tape
3. Prep the cover that goes over the A1's built in LED with fresh tape
4. Remove the old bolts from the back of the gantry
5. Bolt the part to the back of the gantry, using the new, longer bolts.
   1. Use washers for a more secure fit
6. Fit the rest of the LED strip as in the original instructions.
