About this 3D model
IKEA's Rolfstorp LED is the perfect width for the A1. Had one lying around, so I remixed two separate brackets (one model for the A1 gantry bracket, and another for the Ikea Rolfstorp LED strip). Rolfstorp LED section extended by 0.2mm for better (marginally looser) fitment to the LED strip. Mount the LED at the back to allow for clearance to the toolhead, and ensure they're inset enough so they don't interfere with the Z-axis lead screw brackets. https://www.ikea.com/gb/en/p/rolfstorp-led-lighting-dimmable-30520080/
