Not sure if the hole at the 2L section goes all the way through or if there's a stop.

Whan do you think of placing 1-16 chrds to close the gaps at the axle hole in hi res?

Magnus Forsberg [MagFors]

made the following comment.

2021-01-13 20:15:01

Adding ering prims, or 1-16chrd, is a really good idea. But I wonder if it shouldn't be done to the axle prims instead?

Better use npeghol4 instead of npeghol5, would curve corners on both sides of the npeghol

Magnus Forsberg [MagFors]

made the following comment.

2022-09-14 19:50:01

Not possible, since npeghol4 adds unwanted edge lines.

2022-09-14 21:15:02

Should then have new npeghole shape hard-modeled in I guess?

Max Murtazin [SwampKryakwa]

submitted a new version of the part.

2022-09-25 00:35:01

Replaced all of npeghol geometry with a primitive

I can't find any support for a open, nor a blocked hole...

Max Murtazin [SwampKryakwa]

made the following comment.

2022-10-04 19:00:01

Page 9 of BI for set 75335 suggests it is a blocked hole - instead of using a 4L axle, two 2L ones are used

The Builder app shows a stopper inside.

Is it a normal stopping like in 2L axle connectors? Don't know much about variations of those

Max Martin Richter [MMR1988]

made the following comment.

2024-01-10 08:04:47

I would say yes - just a simple thin ring in the middle.

correct there is a stopper inside, when I authored it I did not have the part, forgot to change it

This is perhaps a good opportunity to discuss the error in all similar parts.
The hole needs to be exactly 20 ldu deep, but in most cases it has been modeled with a divider at 19.5, 1 ldu thick.
That's not correct.

All Technic Axle are made using the axle.dat primitive. Or something more suitable, when needed.
That primitive is not correct. A real axle has a slightly bevelled, convex end. Making it possible to have the 2 axles pushed all the way into the stopper ring, wich has a coresponding concave bevelled design

The axlehole primitives in this part need to be 20 ldu deep, to allow a correct position of a mounted axle.
But we need to also have a stopper, 1 ldu thick. It doesn't add up.

When I reworked the axlehole primitive I found that many parts use a primitive that is only 19.5 ldu.
This will be a problem in connection seeking SW, that will not allow a correct position of the axle. The hole isn't deep enough.

Max Martin Richter [MMR1988]

made the following comment.

2024-01-10 18:24:00

All axles I measure are shorter than our models.
2L = 15.7 mm
3L = 23.4 mm
4L = 31.7 mm
5L = 39.4 mm
6L = 47.7 mm
7L = 55.5 mm
8L = 63.5 mm
10L = 79.4 mm
12L = 95.2 mm

(Note that I checked only one piece for every length. I think, it differs a bit from part to part.)

Therefore we should think about reworking the axles maybe?
