Rope clamp, rope clip, Seilklemme - no hardware needed

Description

Rope clamp for dog leashes and similar. Currently, there are two versions:

• file ropeClamp-1-2-8mm.stl to make loops: two ropes at one end, one rope at the other end.

• file ropeClamp-2-2-8mm.stl to make a loop and let the end go through the clamp: two ropes at either end. I haven't tested that version myself since I don't need it.

The clamp is designed for 8mm rope. You can try to scale it for other rope diameters. I probably wouldn't go much smaller for the locking clips to be sturdy enough.

The clamp is symmetrical and clips together with no additional hardware needed. I'm an adult man and was not able to pull the rope out of the clamp.

WARNING! This clamp should not be used to hang heavy or dangerous objects without additional safety measures. Under no circumstances should you use this clamp as the sole means of securing children’s swings, rope ladders, hammocks, etc.

Print two to make one clamp.

NOT FOR COMMERCIAL USE. Not even on Etsy.

Printing

I suggest these settings:

• material: PETG or ABS

• layers: 0.2mm

• perimeters: 8 - this way no infill is created at the walls

• top / bottom perimeters: 1mm or more

• infill: 25% gyroid

• infill top / bottom pattern: concentric

• support: no (tested with Prusa Core One)

Happy printing! Please let me know in the comments what you make out of this.

Assembly

The instructions are for the version with one rope at one end and two ropes at the other end. I haven't tested the version for two ropes at both ends yet.

1. Place two halves next to each other. Consider the orientation: The holes at the ends have different sizes. Place the same size next to each other.

1. Insert the rope so that the end is as far inside the clamp as possible. The rope supports the locking clips from the back, so the housing must be completely filled.

1. Place the second half on top of the other one. Consider the correct orientation.

1. Double check everything. I had a hard time to separate the two halves with a spudger after clipping them together to make the photos. Clip the two halves together. It should make a nice clicking noise.
   
   If you want to be absolutely sure use a bit of superglue. Extreme tensile force is more likely to cause the two halves to separate than to pull the rope straight out.
