These are perfect for many of the spool rack designs found on here that require a 1in. diameter pvc/dowel.

Each rod (not including the screw portion) is 6 inches, 2 pieces equal a foot so delete or add rods as you need. The print profile will make two 4ft rods. These do not need glue or anything, and they assemble very easily.

These rods screw in together tightly and are very sturdy. The rods with no screw head are end pieces.

Made with 8 wall loops, can use regular PLA and will still be strong. They can be resized (by keeping x and Y in uniform scale) as you see fit and will still work

possible uses are up to your imagination
