Helmet and Steering wheel holder with Nuts and Bolts

thingiverse

I made these for my Race Car to hold my helmet and to hold my steering wheel. I used a design off of here and remixed it. The original was created and uploaded by TheEmpty. I found that this was too large of a diameter for my rollbar even though it says 1.75in on the original. I took it remade it and shrunk down the diameter by 2mm also I created the holes to be 1/4 instead of around 3/16ths like they were. I made the part 10mm thinner in order to fit my helmet strap over it. I took the original that I made for the helmet hook and lengthened the actual hook for the steering wheel because the steering wheel was a tight fit for me. Next I made my own nuts and bolts with a .21 inch threaded rod and a 7/16ths bolt head. For the nuts I made them 7/16ths but made the diameter of the threaded hole 1/4 inch to make sure it fits around the bolt. DISCLAIMER, I recommend using regular nuts and bolts, the plastic hardware will more than not likely support your application. Also I used a 60% infill with a .28 layer height for the hooks just to give them more support as they will be holding a helmet while riding through the pits or off the track. For the nuts and bolts I used a 20% infill with an infill line multiplier of 2. For both I used the "triangles" infill setting. This is my first creation on Tinkercad. I got my Creality Ender 3 Pro off of amazon about 1 week ago. As of 1/31 this is what I have created if you have any suggestions as to what I can remix and make better please let me know or remix it. Will add pictures when I can. Updated 2/21. they should be correct to size. try them out and let me know.
