Paracord thimble and rope clamp

Will fit 4mm (~1/8") diameter paracords. Eyelet diameter is 7mm (little over ¼").
Obviously not suitable for safety relevant applications.

Changelog

Four variants available

BOM & additional parts required

• eyelet - 3d print
• clamp plate - 3d print
• screw M3 x 8 mm according to the variant printed
• nut M3
• nyloc nuts possible, but needs longer screw, and no flush fit

Production

The 3mf file includes all basic settings, and works as tested on my Mk3s with standard PETG and 0.40mm and 0.25mm nozzle.

Some adjustments may be needed for individual cases:

• infill is preset to 20% - you may want to change that to your needs
• add supports everywhere, when the screw hole or eyelet don't build up well
• add a brim when the filament won't stick well to the bed
• add variable layer height 0.05mm on bottom and top of the eyelet, for smoother surface
• when using ASA, ABS or TPU, scale the model to correct shrinking compensation

Assembly

0.) Use a tool that suits your chosen screw head. Screw is M3 x 8mm, nut is M3.

 1.) Place the nut inside the cavity.

2.) Place the paracord into the thimble, place the screw in the clamp plate, and place the latter above the cord, tighten the screw for 1-2 turns, adjust the cord to your needs.

3.) Take care not to squash the outer wrap of the cord between the closing edges.

4.) Tighten the screw entirely, so the gap between eyelet body and clamp plate closes.

Please comment if something can be improved, or if it works for you. Also, don't forget to share makes and application examples!
