Notice:

• Still in development!!!

• Don't use it if you are not sufficient educated in bike mechanics!!!

• If you want a precise tool you should buy the original from wheelfanatyk!

• If you print this out it maybe doesen't fit with the other parts or something else goes wrong.
  So you invited to help to develop this by visit: https://www.thingiverse.com/groups/bike/forums/general/topic:28979#comment-1847641

• If you have small hands, you maybe can't use this!

• If you want to know the spoketension, you have to calibrate it by using a force gauge for
  tensile load combined with a spoke tension device.

Update:

• Now you can print the body on a smal printer with a volume of: 120 mm x 120 mm.
• You dont have to print the "spacer" file (it's now integrated)
• You dont need the " thin M4 washers" (they are also integrated)

You'll also need:

• 1* dial gauge with around 12,7 mm travel (and one whitch fit in the tensiometer body)
  I get my one from china like thisor you can use this digital gauge

• 1* linearrail: TSK LMBM9 - rail: 80mm (look for it as used thats cheaper, or you get the cheap one from the third picture. It seems that also fit but I dont know exactly)
• 2* 624 zz bearing
• 1* spring (lenght: 20 mm to 25mm (depends on your dial gauge), outside diameter: 9 mm, wire diameter: 0,9 mm)
• 4* M3 x 5mm countersink screw
• 4* M3 x 8mm socket head cap screw (inbus) screw
• 4* M3 x 30mm socket head cap screw (inbus) screw
• 8* M3 nuts
• 4* M2 x 6 mm screw (depends on the used dial gauge)
• 2* M4 x 20mm lens head screw (maybe inbus)
• 2* M4 nut
• little pice of PTFE-tape (stick it to the bolt which touches the spoke -> to prevent deterioration of the bolt)
• and a wheel to work with ;)

I hope this thing can help people who have special interests in bicycle mechanics.
Just as his inventor would have liked.
So thanks to Jobst and his friends.

Special thanks goes to cmh and QuangVuong who helped to develop this thing!!!
