Abstract
- A dial indicator is a tool used to measure linear displacements. It accomplishes so via the use of a plunger that's constricted to a measured linear movement. Simply, when the plunger is pushed into the body of the tool, the distance it is pushed in is "indicated" on the "dial" face of the tool. This is useful for any kind of precise measurement of thickness, depth, width, and can even be used to ensure a machining device or tool is accurately trammed.

Tools needed for fabrication of the OSAT
- MOST Delta RepRap or similar RepRap 3-D printer
- XX Hex Head Allen Wrench
- XX Open End Box Wrench
TOOL REQUIREMENTS MAY VARY BASED ON NUT & BOLT SELECTION
Skills and Knowledge Necessary to Make the OSAT
- 3D Printing Knowledge & Capabilities
- Understand the needs & application for a dial indicator
- Ability to assemble fasteners and critically aligned plastic components
Technical Specifications and Assembly Instructions
- Download and print the plastic components listed in the bill of materials
- Recommended: Print with a 100% infill at 0.25mm layer thickness or less, print speed may vary depending on printer
- Clean burrs and excess plastic from parts that may be remaining from print
- Align the corresponding components from the bill of materials to the pictures posted below while ensuring:
- All holes align
- All gears mesh together
- L
- Assemble Fasteners so that the head of the screws are on the face of the indicator and washers are on both mating surfaces
- Lightly tighten fasteners so that gears spin freely with minimal slop
- Assemble needle so that needle is spaced away from dial face
Common Problems and Solutions
Cost savings
- 25g of PLA ($0.40 USD) + 3mm Nut ($0.13 USD) + 3mm x 12mm bolt ($0.33 USD) = $0.86 USD Total
- Compared to $4.27 USD Cheapest Hemostats I Could Find
- Cost savings of $3.41 USD (79.9% cost savings)
- The biggest benefit is not cost, but availability when Amazon delivery is not an option in a remote or devastated area.
