Good fit and finish - Nubs November 13, 2017
Reviewer: Al Klesczewski from Suffield, CT United States  
These nubs are being used in our version of the robotics base.  They work exactly as advertised.  My only complaint is the shipping time and cost.  In today's market, it should not take a week to deliver these parts.  When we order parts mid-season, we really need them in 2 days - but we cannot afford the huge premium for 2 day shipping.  Recommend looking at other shipping contracts, or working with Amazon Prime.

Single Use Only October 22, 2017
Reviewer: IH from MI United States  
These are great, but pretty much single use only.  Extremely hard to screw in bolts and even harder to remove them

Great Idea but Fair Execution February 7, 2017
Reviewer: Louis from FTC COACH - TEXAS  
The nub design is awesome especially if you are in a position to use a clamp/collar at the end of your shaft.

When attaching a wheel to a NeverRest motor, these are no so good. The set screw is aimed at the rounded side instead of the flat side of the D-bore.

Results - in driving mode, the setscrew has a tendency to work loose and the wheel will slide from the motor shaft.

We had it happen to two different wheels this morning.

(AndyMark response: We have contacted the customer. They are using 6" wheels and found greater success using the XL Nub.   Having the setscrew press the shaft into the flat built into the Nub was an intentional decision by our design team. This way, we get the best possible torque transmission between the Nub and shaft. The setscrew is also used to hold the Nub along the shaft and for this team, using the XL nub with 2 setscrews has worked better for them.)

great idea January 23, 2017
Reviewer: Anonymous Person from OH United States  
We don't have a lot of burn time on these yet, but since Hubs are easily our teams biggest source of unreliability, we are optimistic this new design will put that behind us.

I wonder if they would be better if the holes were tapped.  We put some together without tapping and some with, so we will see how it turns out.

(untapped, it seemed the edge of the Nub distorted a little more than we liked.  We wondered if maybe that would serve like a locking mechanism, but tapped some of them to compare).

great for people not so good at set screws. January 23, 2017
Reviewer: Anonymous Person from OH United States  
This takes the set screw out of the torque transmission path, so if you don't get it tight, it still spins.  Might fall off, but until then, will keep spinning.

lovin' the nubbin'! January 8, 2017
Reviewer: Tom Gill from PA  
These were perfect for adapting an AndyMark motor to some Mecanum wheels.  The D-shaped hole means no more axle slippage.  I wish all our hubs had this geometry.
