Hi. I am sharing my new project PRECISION DIAL INDICATOR on wich I worked over 3 months. You can use it to bed leveling in your printer, measure runout, use on CNC machines etc. or ... have an interesting gadget :). For a long time i was looking for how to minimalize backlash. I was able to achieve 0.02 value of about. Please see presentation:

In my opinion this tool is very easy to assembly, but requires a good printer calibration. I tested PRECISION DIAL INDICATOR on my Ender 3 PRO but also ordered testing on other 5 different printers and 5 different users. It may be required to reprint some parts with another settings in the slicer. If the mechanism is not moving smoothly I think the best way to fix it is reduce external wall (for example by less flowrate or by using scaling).

Specyfication:
- unit mm,
- resolution 0.01 mm,
- range 14 mm.

To assembly DIAL INDICATOR you must have:
- 2 screws M3x25 (or longer),
- 1 screw M3x16 (or longer),
- 3 nuts M3.

To assmebly HANDLE to dial indicator you must have:
- 1-3 srews M5x16 (or longer),
- 1-3 nuts M5 (wing nuts are the best).

DIAL INDICATOR:
Total Build Time: ~5 hours
Total Filament: ~0.026kg (~9 m 1.75 mm)

HANDLE:
Total Build Time: ~3 hours
Total Filament: ~0.021kg (~7m 1.75 mm)

I designed this parts to use nozzle 0.4 mm and layer height 0.2. Every of parts I printed with this settings:

Material: PLA or PETG

Layer Height: 0.2mm

Nozzle: 0.4mm

Infill: 20%

Use support only in 'DIAL'. I recommend to use max. 0.15 mm/s speed on the first layer.
