bed slats holder

Many people use the LR and double centre, but the clipon is just for 30x30 square tubes. My bed is a double from Argos. They grew weak, and when I purchased replacements from BBQ, they were longer than the originals. These printed ones save time while cutting and provide added stability between the slats. So you may double down if you're a big man like me. You may also zip tie the two non-clip ones for added security because they have space for it.

print with 3 layers and 60% infill, I print mine on 5mpro FF and 0.6 nozzle. no supports needed just flip them to be priced on their side.
the designs do have holes fro screws but you do not need them, never had to use them myself
