Introduction: Organising Clock
Here is my clock that is made for organising your time better.
It is made so that the face of the clock is magnetic and able to stick magnets to. These magnets will be the same colour as the small tabs on the side of the board, the point of this is to have the coloured magnet placed somewhere on the clock where you need to do something, then which ever colour the magnet is, write on the small board what to do in that hour. If that is confusing here is an example: I stick a blue coloured magnet on the face of the clock at 9 o'clock and next to the small blue coloured tab I write on the board (because it is a white board) "I need to do homework". So now when I look back at my clock later I know that at 9 o'clock I need to do homework.
This clock is for a student or a family. If you are usually on time with tasks that have to be done but sometimes can be forgetful about other tasks that need to be accomplished then this is for you. This clock is simple and an understandable clock with an attached board for the people to write their tasks, deadlines, appointments etc. Everything used in this design is affordable and are things that can be found in shops or at a school.
Step 1: Create the CAD Files
The first step is the create the CAD files. Try to create them to look identical to the ones shown. Additionally, add some numbers on the white acrylic CAD files to later stick on the clock.
- The circle (the clock face) should fit perfectly in the shape in the other photo.
- To colour everything in red that needs to be engraved and everything in blue that needs to be cut.
- The numbers on the clock's face should be perfectly spread.
- The hole in the middle of the clock's face is big enough to put the clock mechanism in.
- The long side of each small trapeziums should fit to one line on the rectangle on the other picture.
Make sure to laser cut the picture with the clock in MDF wood and the other in white acrylic.
Step 2: Cut the Magnetic Sheet
Once the CAD files have been 3D printed and in the right size, you can commence in cutting the magnetic sheet. This sheet is made out of steel so if necessary wear protection and be careful of surrounding people. This sheet of steel is to go onto the face of the clock to make it magnetic.
- To make the cut out perfectly circular.
- To make the cut out the same size as the clock's face but half a centimeter bigger so that it will fit onto the stand later.
- That there aren't any bumps on the side of the cut out.
Because steel is very hard to cut (especially when you're trying to cut curved lines) you will need to do some filing after to smoothen the edges (as can be seen in the photo). Try to put the steel in a holder so that it won't bend while filing.
Then using a 10 mm drill, make a hole in the center of the clock (to put the clock mechanism in).
Once it is cut stick it to the wood using epoxy resin glue.
Step 3: Bend the White Acrylic
Using the the largest piece of white acrylic that was cut out, you will now need to bend it to make a stand for the clock. As can be seen in the picture you will need to make two bends, one 90° angle and another obtuse angle. For this step a strip heater will be needed. Be careful with it and if possible be under supervision if this piece of equipment is unfamiliar. Make sure to wear gloves to prevent getting burnt. In the CAD files there were two lines that were engraved, these are the two lines that will be bent. The first line that should be bent is the one furthest away from the curved edge because it needs to be a 90° angle and by doing this one first, it will make the other one easier. Start by lining it up on the strip heater and waiting for 2 minutes for it to become flexible. As soon as it is ready, press it against a surface with a back and press for about 30 seconds before it has cooled down. Heat the acrylic again for the same amount of time but on the other line. This bend should be the same angle as seen in the picture. To prepare fill a tray full of water. Once the acrylic is ready, bend it into the obtuse angle and dip it into the tray for 10 seconds.
To test if the stand works use the clock to rest it on. Because the steel is slightly bigger than the wood it will now be better supported by the stand.
Step 4: Painting + Stick Parts Together
Before you stick everything together the small trapeziums and magnets need to be painted in different colours.There should be the same amount of trapeziums to magnets and be put into pairs. Each pair should be painted a separate colour. Once they are painted stick them to one side of the white acrylic board using epoxy resin.
Now, again using the epoxy resin stick the numbers on the steel. Try to use a protractor to ensure that the numbers are stuck around the face evenly.
Step 5: Finishing Details
To finish the small board, use a wax crayon to show the enrage lines more clearly. The colour of the crayon is your choice and you should use whichever to personalise your clock.
To finish the clock and allow it to work, put the mechanism through the hole in the middle of the steel and wood and use the hands to put on top. To allow the clocks to show the time put the batteries in the back.
