K'Nex Length Guide

I enjoy building with K'Nex. This guide helps me know what sizes are next. Sometimes a red rod is not quite the right length. Here you can see that a yellow rod connected with either a green rod or a white rod using a regular connector is next in size (down or up).

The other picture shows an unusual connector called a 2-way Straight H-clip. This is included in some Micro-K'Nex sets. Using these shorter connectors can make adjusting lengths much easier. However, not everyone has these H-clips available.

I have one of these "Length Guides" by my storage drawers. I have looked at this many times. It has helped me, perhaps it can help you too.

Here is a list of the parts

Rods:

• 2 grey
• 3 red
• 5 yellow
• 5 blue
• 7 white
• 7 green

Connectors:

• 16 yellow
• 12 orange

Put 1 yellow connector onto one of the grey rods using one side of the connector. Put the rest of the yellow connectors onto the grey rod facing the same way. The spacing does not matter yet since these will have to be moved as part of the assembling process. This will be the holder for your guide.

Having the yellow connectors on the grey rod in the completed assembly, the sizing is more visible. This is only important if you expect to keep one of these around for a while. If not, just save the image of mine so you can reference it later.

I put the longest rod into the yellow connector for my guide. Only one of the green rods needs to go directly onto the yellow connector as all of the other green rods will go on the top of the other lengths.

Put one green rod on the first yellow connector as this is the shortest length possible. Attach all of the other green rods into their own orange connector.

Put one white rod on the second yellow connector. Attach three of the white rods into their own orange connector. Attach three of the white rods into an orange connector that already has a green rod on it. There should be 3 orange connectors not used yet.

Put one blue rod on the third yellow connector. Attach one of the blue rods into an orange connector. Add one blue rod to an orange connector that has a green rod, and another to an orange connector that has a white rod. The last blue rod should be attached with an orange connector to one white/green assembly which will make the first assembly with three rods. There should be 1 orange connector not used yet.

Put one yellow rod on the fifth yellow connector, leaving the fourth yellow connector open. Add one yellow rod to an orange connector that has a green rod, and another to an orange connector that has a white rod. Add one yellow rod to an orange connector that has a blue rod The last yellow rod should be attached with an orange connector to one white/green assembly which will make the last assembly with three rods. All of the orange connectors should now be in use.

Put one red rod on the ninth yellow connector. There should be three empty yellow connectors between the yellow rod and the red rod. Add one red rod to an orange connector that has a green rod, and another to an orange connector that has a white rod. Put the grey rod in the sixteenth (which should be the last) yellow connector. This is as tall as this guide will go. There should now be ten assemblies waiting to be added to the holder.

Put the assemblies on the yellow connectors in order of height. Here is the order which includes those already in the holder:

1. Green rod
2. White rod
3. Blue rod
4. White/Green rod
5. Yellow rod
6. Blue/Green rod
7. Blue/White rod
8. Yellow/Green rod
9. Red rod
10. Yellow/White rod
11. Blue/White/Green rod
12. Yellow/Blue rod
13. Red/Green rod
14. Yellow/White/Green rod
15. Red/White rod
16. Grey rod

Now the spacing can be done. I leave an added space between #8 and #9 as a reference. Enjoy, and Happy Connecting!
