3D print a steering wheel to go over an arkanoid spinner

[menace]

So the only knob I had was an arkanoid one pulled from the parts bin.  I didn't want to pay $70 (CDN) for a factory one and besides my 3d printer has been just sitting there looking at me so what the heck!  The idea here is that the arkanoid spinner lives attached and when I want a steering wheel i just push this one on..seems a snug fit for now.

As the notes say, its meant to gover a knob thats 39.5mm in dia. and the wheel itself is about 140mm in dia.  I may make a smaller one depending on how this one feels.  I also added a larger counterweight to the bottom of the ultimark spintrak spinner to give it more heft.

My first print failed due to a snapped belt    So I modified the thing to be in two parts so its easier to at least get part of it done LOL  --Its currently on round 2...I also made the wheel 135mm

3rd time's the charm!  My receiving cup was a smidgen too small--I made it at 39.5mm but it printed at 39.2mm so some sanding is in order.  I resized the piece on thingiverse to be a bit oversized.

Interesting. How strong/durable is the 'stuff' these 3D printers kick out, though?

[menace]

Its good enough for its intended use (home use only as a spinner)  Some guys actually use them on go karts--full size though    If you have a good infill, the piece will take quite a bit of abuse

PLA or ABS, or something else?

My PLA prints tend to break fairly easy (might be my printer settings though, and the brand PLA).

I don't see strength being an issue here.  It's a small wheel slipped over a spinner on a stand up cab.
The spinner isn't going to offer any resistance and there's no reason to push or pull on the wheel.
It's not like people are going to be pulling on it to get in and out of a sit down cab.

My PLA prints tend to break fairly easy (might be my printer settings though, and the brand PLA).

Things printed with 100% infill are pretty tough.
I test printed a router table insert at 25% a few weeks ago. 
It fit too tight so I had to use a screwdriver to pry it out.  It deformed super easy.

I'm curious how smooth it would turn out if you sprayed it with plasti-dip.

Another option to consider is print-smoothing epoxy.

Sure, but 100% infill takes ages to print...

100% infill is never a good idea.  The strength difference between 100% and 80% is barely measurable.  Not to mention the expansion and contraction of semi-liquid plastic extrusion needs a little room to breath while printing.
