Instance of Crawler harness holder
OKH Manifest Open Know-How Manifest Download

Crawler Harnesses can be cumbersome to keep in your tackle box without a holder and more often than not, if you're walleye fishing, you have a tackle box FULL of crawler harness holders just to keep up. Instead of buying out Dick's Sporting Goods, or not having a place to buy these holders nearby and getting them all tangled, why not print one of your own? This 3D printable crawler harness holder just needs foam or cork to make it very useable as it is a very easy print.

Bill of Materials[edit | edit source]

  1. 28m of filament- $1.68 ($20 MatterHackers Build Series and about 330m per kg so $0.06 per meter)
  2. 1 Tube of super-glue- $0.59
  3. 1 square foot of foam or cork- $1.30 (4 pack is $5.19 on Amazon)

Total: $3.57 or about $0.43 cheaper than a standard one

Tools needed[edit | edit source]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Cutting tool such as scissors or a knife

Skills and knowledge needed[edit | edit source]

  • 3D printing

Technical Specifications and Assembly Instructions[edit | edit source]

  1. Make sure one end is down on the build plate when slicing, no support should be necessary
  2. I printed this at 80 mm/s with 25% fill and 0.6mm wall thickness, it shouldn't need to be any stronger or more precise
  3. Keep the layer height small to avoid the need for supports. I would recommend 0.2mm layer height
  4. Print should take about 2.5 hours depending on your speeds, infill, wall thickness etc.
  5. Once print is completed, cut 3 strips of foam or cork to fit the three smaller diameter sections
  6. Glue and use a rubber band or masking tape to hold foam or cork in place until adhesive is dry
  7. Assembly should take about 10 mins plus additional time for the glue to dry

Common Problems and Solutions[edit | edit source]

  • Avoid adhesives that will not adhere to plastics (like PLA) or foam or cork. This could cause the foam or cork to come off of the main printed part. Instead use a cheap, strong adhesive like plastic epoxy or super-glue.
