Two Finger Knuck - Simple 3d design and modeling - Fusion 360 File

  • Status: Closed
  • Prize: $20
  • Entries Received: 33
  • Winner: makhan22

Contest Brief

Wanted: designs for two finger knucks. I would like the design to be mirrored left to right as I plan to mill both sides of this, so both sides (left/right) need to be exactly the same in look and actual distances. Basically completely symmetrical.

Length - Approximately - 2.5" or more - You may want to consider adding some distance in the back where the palm grips the knuck.
Width - Approximately 3"

Please consider the ergonomics of holding the knuck.

Design does not have to be elaborate or simple, submit what you believe is good.

Thickness - .4" across the entire knuck. This dimension is set.

Primary Finger Hole Diameter - .75"

Lanyard Hole Diameter - 3/16"

All edges should have a radius. You do not need to show this radius or the countersink in your jpeg, however, it will be required for the final STL submission

Edit... In the Z (vertical) plane, there should be no hidden surfaces, I use a CNC machine to cut from the top and bottom.

Submission should be jpeg format. The jpeg can be an image of a Fusion 360 File.

Final submission after award should be Fusion 360 File format.

    Greg- i've actually modelled these designs by taking reference drawings of knucks, i understand it seems as if the bottom portion of the knucks 27 - 30 seems a bit large for holding, if u like the overall look of the knuck, i could tweak the dimensions

      Gavin - That is what I am doing. The designs you are presenting are not very practical. These are supposed to be worn like brass knuckles. In many of your designs, I do not see how they would even fit on the hand.

    please let me know ur primary area of concern, is it the ergonomics of holding the knuck, if so i can tweak the dimensions of my models or r u concerned with the look of the knuck

    the pics that u've rated 5 stars are all so varied, so i'm not being able to understand what kind of design u would like, perhaps u could help me out by giving any reference images for modelling or a simple hand drawn sketch

      but there is one reconsideration. you have mentioned you prefered dimensions and i tried to use those. i can reduce those to add more relief on the sides for other fingers as some entries already done above.

    I've added some additional images for consideration. The knuckles do not need to have a bottle opener.
