Leds holder designed for Hirobo Bearcat SS designed for thos cheap led buckets you can find on aliexpress, ebay or amazon.

Printed fronts in TPU (but PETG is fine as well as the part won't be too much exposed) and rear in ABS. All printed without supports, in 0.20 layer thickness. You'll have to drill the fixation hole on the front with a 3mm drill bit and the led holes with a 5mm drill bit at the rear. It was done this way to avoid printing supports.

License plate is the one you can get from Tamico.de in 15x30 mm format.
