DIY Helping Hand (Third Hand) - Build Video

In this video I will show you how I made my own DIY Helping Hand (Third Hand) using a door stopper and flexible coolant pipes. So if you are also tired of using a cheap and crappy helping hand from the hardware store then grab some material and build your own. The build can be done in 2 or 3 evenings and the material cost is below 20 EUR (22$).

Material list:

- 4x Shrinking tube diam. 7mm, length 15mm each (Schrumpfschlauch Durchmesser 15mm, Länge je 15mm)
- 2x Insert (3d printed) - see link below
- 2x Hexagonal plug (3d printed) - see link below
- 1x Cap (3d printed) - see link below

Links to the free STL files:

Print settings:
Insert: Layer Height 0.2mm, Infill 25%, Support: yes, Brim: no (Note: the side with the small diameter should be on the print plate)
Hexagonal plug: Layer Height 0.2mm, Infill 15%, Support: no, Brim: no
Cap: Layer Height 0.2mm, Infill 15%, Support: no, Brim: no (Note: set bottom and top layers to zero)

Special Tools:
- Forstner bit diam. 30mm
- Forstner bit diam. 20mm
- Drill press
- Disc sander
- Heat gun
- 3d printer

Camera:
Sony HDR-CX730

Microphone:

I have made a STL for a one-part all 3D printed, I cannot load picture but if Bavarian RC whant to share to other ask me, I will send them all ! Thanks for the very good idea !

Great project and well-presented. Is there an entry-level 3D printer that you could recommend to get started using one for model aviation projects? I am in Florida.
Thank you.

Really? You made THIS and you used 20.000 bucks technology? Are you serious? Only if you can't find anything similar on the market, or it is too expensive, that is OK. And you used A LOT of things, even a 3D printer, to make 2 pieces of clamps? Really? You can buy for 34$ the third hand with 3 hands, with a solder stand, with the paste/sponge/wire stands. With the magnifying glass.
And the Chinese thing you threw in the garbage, it is very practical and cheap, it is your problem that you loosen all screws and you are surprised that it is like a limp dick. You can add some rubber washers, you can get any pressure you want, and even a pit bull couldn't take your wires from you. But, you choose to be smart. To make 10$ thing with machines of 20.000 bucks. Congratulations.
