UPD 21.10.2016 Added CDR files for laser cutting.
Wood box with secret mechanical lock.
This toy will protect your candies from being eaten by stranger :)
Ideal for protect your candies from children or small sicrets from anyone.
Assembly: DIY or I will assemble it for you.
Assembly time: 2-6 Hours
Materials needed for assembly:
1. Wood glue
3. Sand paper
Additionally 4. Inc for colouring or making custom key-symbol5. Varnish
To make parts:
1. wood or plywood;
2. saw or any cutting device.
Next instructable will give you idea how to build this box by yourself.
I hope that this small tutorial helps you to assembly 3D-puzzle box.
Check complexity like in photo.
4 nails for wheel and 1 nail for box
7 parts of external box (left)
5 parts of internal box
Step 2: Grear Assembly
For assembly you’ll need wood glue, sandpaper and file
Take one of 4 nails and one gear.
Add drop of glue inside circle on a wheel. Insert nail on circle.
Remove needless of glue using paper towels.
Wait 10-15 minutes for glue dries.
Step 3: Internal Box
Next we will assembly internal box.
First time try to assembly parts without glue.
Do the same with glue.
Add glue to each tooth on both parts.
Press on right position.
Do the same with the other part.
Note that in 10-15 minutes glue will harden.
Step 4: Small Tuning of Internal Box
In the next step we will need file.
On assembled internal box we must make little cutting for excellent work of lock.
Do the same like on photo below.
Look on this photo for cutting.
Do exact like in photo.
Check quality of cutting using one of wheels.
The arc-part of wheel should not be greater than wall of internal box.
Note that I cut only from one side.
Step 5: Finishing Intenal Box
Add finally nail to internal box.
Add a little glue to box-nail and install it on its position.
Step 6: External Box
On this step we will build only part of external box.
When the glue will harden we will assembly lock part.
Step 7: Lock Construction
Insert all 4 gear+nail-part on holes of this part. Note that this is not glued particle in this moment
Step 8: Lock Constraction Step2
Check notes on photos.
Lock system installing.
Take this part. (photo 2)
Add a small drop of glue inside the circle. Note that this part must be fixed to gear+nail part and not to top-box-part. When you’ll rotate gear you’ll rotate this part too.
Next install 4-symbol code what will be your key-number.
Fix it using hand and rotate whole top-box part. Add wheel to nail on this position exact like on photo. I add small piece of paper to prevent contact glue with top-box-part and wheel-part. Also when you remove this piece of paper in 10 minutes gear-nail-wheel par will spin easily.
On photo there are all 4 gear-nail-wheel on position. This is opened position, your key combination.
Now I’ll make little explanation. On photo_8 wheel on bottom is on closed position and wheel on top is on open position.
Step 9: Final Assembly
For easiest assembly on this step I’ll place internal box on its position in external box
Than add the last one unused part with holes on its place without glue!!! In this moment we will test how the lock works. Then add a top-box part with gears and wheels.
In this moment check you key combination by rotating gears. If all fine than fix this both parts with glue. Add the last one part.
