tosjduenfs' Cable Chain With Rounded Edges
by QuentinT, published
This is the same part as tosjduenfs' cable chain, but with added fillets that make printing easier. The original thing had hard corners, so when I printed at high speed on my machine, the parts did not line up due to backlash. The new rounded edges should reduce the oversized corners because the printer can smoothly accelerate around corners.
The cable channel is 1/2" wide and 3/8" tall. Each link adds 1/2" to the chain. The folding diameter is about 1 7/8"

Print as many links as you need to make the desired chain lengths. Turn each link 90 degrees to the previous link, so any error in your printer will be canceled out, and your chain will remain straight.
I printed mine at .25mm layer height, 2 walls, and .25 fill
I included both the stl and solidworks files in case you wanted to make your own modifications
