How to Make Best Connectors in Tinkercad

So again we are here in a new instructables and today we are going to to learn how to make good connectors in instructable.

Today I will discuss with you about good type of connectors which can be used in many projects. All the three connectors are made by my students.

The first three steps are actually the basic concepts for creating connectors but if you want only the connector send please skip them and move to the fourth step but you want to learn some concepts then check them out too.

So let's start...

Supplies

Tinkercad

Step 1: Starting With Basic

At first you should know the concept to make a connector. Actually you are going to make two different parts, among which one is going to fit inside the other, joining both the parts together.

Always the basic thing you have to keep in your mind is that measurement very important. The difference between the measurement of convex and concave part of your connector should be at least 0.5 mm.

Step 2: Making Connectors Easy to Detach

One of the most important part for connector is it should be detachable. Connector are use many times and they need to be something which would make disassembling easier. Your connector should be design in such a way that you can detach both the parts.

Step 3: Lubrication and Movement

If you are designing connector which makes two parts movable then you need to have lubricated surfaces. do this is not possible with 3D printing you will have to work a little for making the printed surfaces smooth. You can even use synthetic lubricants.

The other most important thing is space between two different parts of a connector. When making a movable connector you actually require free space but the space should always be from 1 mm to 1.5 mm. Which means the difference of dimensions of convex and concave parts of a connector should be from 1mm to 1.5mm after lubrication.

Now according to this lecture now we will see 3 different connectors designed by my students.

Step 4: Blick - Connector Which Makes Things Movable

This connector design by me and my student Vishnu. This was a difficult job and actually we went for designing this special joint for a special purpose. Actually we wanted special kind of joint to fix it in one of our 3D robot model.

We have design joint keeping in mind to very essential things-
(i) it should be detachable for easy disassembly
(ii) it should give movement of 180° in both clockwise and anti-clockwise directions.

Our connector can be said as a advanced version of socket joint.
This joint is made up of box and sphere shapes. You can use this joint in any movable 3D project or toy. It is easy to use and detachable. We have also tried of using it in safety belts as a connector.

Step 5: Buckle Joint

This is Designed by Raj. He is a new student but he is good at cad. He has made this module of buckle joint with 3 square clips of different sizes.

This is a free to use project so follow the link and tinker project as per your need.

Step 6: Liner Snap Connector

This is my student Sneha's project. She has made this project by replicating snap connector from suit case.

Though the measurement and planning are all her own. She has made this connector by understanding the mechanism and designing the connector herself.
