5x112 Wheelhub for Rim Display

I wanted to put one of my old car wheels on Display, either on the wall or integrate in some furniture, but still use the original screws. 

As I couldn't find something like this, and don't want to buy a standard wheelhub, I've designed this kind of wheelhub that fits my current Rims, having the right bolt sizing and radius (5x112) with a center hub of 57.1 mm in diameter.

It can be fully printed with existing M14-1.5 Threads, either as the 18mm thick version, which should take the bolts complety, or as 6mm version, that have enough thread to hold the bolt but still need clearance at the back as the bolt will stick out.

Or print the version only havong holes ready to be tapped as shown in in pictures:

The idea is to screw it on some 18mm plywood with 3x20 woodscrews. The Bolt Holes are 12.5mm, ready to be taped with an M14-1.5. It is better to tap the Threads an not print them, this way the Threads line up with the plywood and have a better fit!

There is a small Indicator on the outside bottom that helps to realign it correctly if the printed hub is removed from the plywood, e.g. for fixing the plywood to the display location, just draw a line on the plywood where this indicator is:

It has a center pinhole of 10mm to place it exactly on the plywood, using a 10mm shaft.

The wheelhub can now be mounted wherever it is desired just using woodworking techniques.

It can be used to mount any Rims that have a 5x112 bolt spacing and an 57.1 mm center hub.

Note:

This wheelhub is intended to be screwed on plywood, cut out with a templating bit in a router and tapped with M14-1.5 to use the original screws. I recommend using plywood and not print it full size in plastic as the Bolts might not hold the weight of the Wheel. Printed threads hold surprisingly well, but still not as much by using the plywood as a backer. The wheelhub can be printed from PLA, as it is just for alignment, all the bolt force are taken by the plywood. And the plywood can be glued, screwed, nailed, etc. to anything without big efforts.

Printing recommendation:

• just PLA is fine
• 0.4mm nozzle
• min. 5 walls for support of the Threads (min. 6 when using a Tap)
• top layer thickness should be at least 1.5mm
