The Laughing Cyclops - Optimized Bike Wheel Truing Tool

This indicator will help you true your wheel!

Simply attach to the frame of your bike or your truing stand and adjust the knob as needed.

I was able to use it in several ways: 

By sound as my PETG tip had a lot of friction.

By wobble when i  leaned the tip onto my V brakes.

By shadow of a light aimed at the tip.

And of course you can just look at it.

• 
• This is not how you would normally use it, but it was nicely visible

FEATURES:

• Small yet fully functional 
  • about 9g of filament for a set
  • I even made custom 3D printable threads to make it smaller
• Can be attached to both thick and slim frames
• Many attachment options
  • Use a rubber band, rope, hair tie, zip tie… anything goes and in many ways
  • You can decide how tight you need it by selecting a slot
  • I have added a version with more slots but the single slot variant is more than good enough
• No post processing 
• No supports needed

HOW TO PRINT:

Print one holder and one bolt - that's a set. 

Print 2 sets max. per person. Don't overdose on truing tools, please.

Do not make the bolt too hollow or it snaps easily.

PETG had a lot of friction in the threads and needed to be worked in a little to run smoothly.

Food for thoughts:

I think if i were to start from scratch, i would rather make use of some flexible print in place dial indicator.
With some sort of small firm clamp to hold it, that would be a really interesting idea. This one did the job for me so i no longer feel motivated to go that far. If anyone were to take this idea further, let me know. There is currently only a single print in place dial indicator design around which utilizes flex that i found and it would not be ideal for this use. A new custom one would have to be made.
