​Animation punchers range in price from between €150 to €800 Euro. There are two types of punches and pegs, ACME (Two rectangular pegs with a round one in the center) and Round (Three round pegs). There is no difference between them except that we can make our own round holed puncher and pegbar for under €25.
MATERIALS
– 3 Single Hole Punchers– Drill
– Screws X8
– Wooden Ruler/Bar
– Wooden Platform
– Wooden Plank
– Paint (Optional)

Software
– Blender
MAKING THE PEGBAR
Step 1:
Download Blender 3D. Open up Blender, once open go to the “scene” tab found on the right in the horizontal row of icons beneath the hierarchy. Once open change units from ‘none’ to ‘metric’.


Step 2:
Now that Blender is in metric units we will need to be able to see these measurements as we model our pegbar. At the top right got to ‘file’ -> ‘user preferences’ -> ‘Addons’ then search “Measure” and enable the Measure Panel addon by ticking the square box.


Step 3:
Now to begin making our pegbar. Measure the diameter of the holes punched by your puncher. If you don’t have the punchers yet the standard punch diameter is 6±0.5 mm. Press N to bring up the transform toolbar and activate the Measure Panel found at the very bottom. This will now measure distances from the origin when you click.


Step 4:
Model your pegbar starting from the default cube by selecting it, pressing tab, click on a face and press E to extrude. Select the entire model in edit mode and drag it to the side until the origin/pivot point is at one end then click on the other to measure the length of your pegbar. It should be between 24 – 26cm.
Step 5: 
Go down to ‘add’ on the bottom toolbar (Make sure you are in object mode or it won’t be there) and add a cylinder to use as a peg. Drag it to the center of your pegbar. Scale it up or down till it has a diameter of approximately 6mm. Also make sure the peg isn’t so tall that it will make drawing difficult.


Step 6:
Once one peg is complete go to the panel on the left and duplicate it. Use the transform arrow to slide the new peg to the left and repeat this for the peg on the right. Now select all three pegs and your bar and press CTRL + J to join everything together.


Step 7:
Once everything is joined together your pegbar is complete. Now it just needs to be exported as a .STL for 3D printing but first we need to add a triangulate modifier. Go back to the horizontal row of icons on the right beneath the hierarchy and select the modifiers tab, go to ‘add modifier’ then ‘triangulate’ and be sure to click apply. If you want to see what this did go back into object mode.


Step 8:
Go to File -> Export -> .STL and make sure that the apply modifiers box has been checked in the panel on your left.


Step 9: 
Once you have your STL file go to Shapeways (or another 3D Printing website if you’d prefer) and upload your .STL pegbar file. Choose a strong material and be sure to double check the measurements of your model before paying.
MAKING THE PUNCHER
STEP 1
Push the pegs of your pegbar into the bottom of each puncher and then place your pegbar on either side of your platform with the punchers in it. Now trace around the punchers lightly with a pencil.

STEP 2 
Remove the punchers and now on the opposite side of each of the three traced rectangles drill a hole twice the width of the punch. Make sure to stay within the traced rectangle. This hole will let paper fall out.


STEP 3
Drill each of the punchers down in their original traced positions.


STEP 4 
Superglue the wooden plank to the tops of the three punchers so you can now punch all three at once by pressing down on the plank.


STEP 5
Finally screw your wooden ruler or bar along the edge of the platform so that you can line paper up each time you use the puncher.
