Project Description[edit | edit source]
Our team decided to create PCB utility tool. It encompasses a vise and many other tools that allow for PCB designing and troubleshooting easier. The vise has many attachments that can be used with or as a stand alone item. The link can be found at PCB Utility Tool NIH
Attachments:
- Vise
- Magnetic Head
- Magnifying Glass
- Light
- Alligator Clips
Testing[edit | edit source]
- The maximum width a PCB can be is 17cm.
- For 3 joints in series the maximum weight it can support without losing shape is approximately 12 ounces.
Additional Materials Needed[edit | edit source]
- 2 small screws (for the magnetic attachment)
- 2 sets of bolts with wing nuts (used to tension the vise arms)
- A small magnet with a counter bore
- Alligator Clips
- Flashlight
- Magnifying Glass Lens
- Metal Hose Clap
Printing Directions[edit | edit source]
- All items were printed with 1.75mm PLA
- The light and magnifying glass will need support
- When printing the ball joints make sure to change the minimum
time on a layer to at least 10 seconds to stop warping of the ball
Assembly Instructions[edit | edit source]
- When assembling ball joints you need to smooth out the inner diameter then
take a mallet and lightly tap the next joint in place
- for the magnetic head a small screw is needed to attach the magnet
- for the vice two sets of screws and wingnuts are needed to attach
the arms of the vice
Cost[edit | edit source]
| Item | Quantity | Grams Per One | Total Grams | Price |
|---|---|---|---|---|
| Base | 1 | 112 | 112 | $2.464 |
| Joint | 10 | 5 | 50 | $1.10 |
| 3 to 1 Splitter | 1 | 17 | 17 | $.374 |
| Magnifying Glass Attachment | 1 | 14 | 14 | $.308 |
| Magnet Head Attachment | 1 | 3 | 3 | $.066 |
| Alligator Clip Attachment | 2 | 2 | 4 | $.088 |
| Flashlight Attachment | 1 | 25 | 25 | $.55 |
| Vise Main | 1 | 25 | 25 | $.55 |
| Vise Arm | 2 | 17 | 34 | $.748 |
- based on $.022 per gram
A Panavise model 201 costs 30 dollars on Amazon. For just the bass and the vise the cost is $3.76. This is roughly 12.5% of the original cost.
