3D Printed Wheel (Press Fit) for Jameco Motor

I love using the Jameco gear motors for various projects, but have always had challenges connecting the shaft to whatever I was making.  Using a 3d printer (MakerBot Replicator) and TinkerCad software, I have come up with a press fit wheel that pushes on to the Jameco motor shaft. In this instructable, I'll show you how I designed the wheel.

The print file is at Thingiverse.com:

Step 1:

Notice the flat spot inside the hole--that's what makes this wheel fit well.

where did you get the 3d printer from? im wanting to buy one (like reprap?) that has the full kit. cant find any...

I ordered mine from MakerBot--you can get one in a week or so from them. The Replicators are made in the USA and their customer service and community help are outstanding!

I don't have first hand knowledge of any others, but I know the Solidoodle is less expensive (long lead time) and I can't speak to customer support. If you happen to live in NYC, they are looking for interns and include a printer as part of the compensation.

CONGRATULATIONS right back at you :-)

You got Featured and Front Page too.

You have to consider the elastic properties when making
an interference fit on / in the oblong hole very tricky stuff !
