Rope clamp with teeth (CC-BY-NC)

Rope clamp for ropes. Fixed with two screws. Has teeth to hold the rope. <a href='https://ko-fi.com/T6T4DXTSD' target='_blank'><img height='36' style='border:0px;height:36px;' src='https://cdn.ko-fi.com/cdn/kofi4.png?v=3' border='0' alt='Buy Me a Coffee at ko-fi.com' /></a> ## Why I bought materials for a hanging planter but realized at home that I forgot to buy rope clips. ## Design Details Rope clip for 4mm, 5mm, 6mm, 8mm, 10mm rope. Comes with two screw holes. Clamp has little spikes inside for better grappling the rope. Intended for use with a rope made from soft material like PP, sisal, or hemp. If a steel wire should be used, I'd recommend a store-bought metal wire clamp (You can also call this a Seilklemme or Drahtseilklemme if you are into fancy German words). If you need a version without spikes, you can resize the included cylinder in the slicer, move it in the hole, and remove the spikes by making the cylinder an infill mesh with wall count, infill, and top/bottom layer set to zero. Due to the way the rope is fixed, the rope ends will be some millimeters apart. A metal clamp pushes the rope ends tightly together but that doesn't work with this printed part due to the way the ropes are clamped. This might make some space problems when used with a tackle and block because the running rope might rub on the static rope. Thing has chamfer of 40° for printing without support material and better looks. Full assembly clamp included for reference but not intended for printing. Spike test file is included if someone wants to test how the spikes might come out during print. Even tiny deformed spikes help to hold the rope. So don't worry if they look squished. I have tested and used only the clamp version for the 6mm rope. The remaining rope clamps are there for a bigger variety in parts. ## Print Instructions Select the needed files. Make sure you have the <i>top</i> and <i>btm</i> file of the same clamp. Nozzle 0.4mm or smaller. I printed with 0.4 and it was fine. Print with spikes up. Print with high infill percentage, e.g. 30% grid. Use supports. Other material than PLA, like ABS, might be even sturdier but not tested. Two screws and PLA seem to work fine for me. Designed for FDM printing. ### Materials Needed Depending on the selected files, a screw of M3 <i>xor</i> M4 is needed. Screw needs to be about 15mm long for the 6mm rope clamp. Select fitting nut as well. A good screw length that makes it easy to insert the rope while the clamp is open is the height of both clamp parts, plus the rope diameter. For the 4mm rope clamp, that's about 4.1 + 4.1 + 4 = 12.2mm. Select a screw of about 12mm length. For the 10mm rope clamp, that's about 6 + 6 + 10 = 22mm. Select a screw of about 22mm length. <ul> <li>2x screw M3 <i>xor</i> M4. <li>2x nut M3 <i>xor</i> M4. <li>(optional) 2x washer M3 <i>xor</i> M4. <li>(optional) Soldering iron or similar to sink the nut with heat if print tolerances are loose. </ul> ## Assembly Instructions <ol> <li> Print clamps and remove supports. <li> Insert nuts into nut holes.
