Introduction: Carter's Lasercut Tank - StuG III Ausf. F
This is my second tank ! the german Sturmgeschütz III Ausf. F (or the StuG III F). This instructable shows you the steps to follow so you can build your own.

The material you need for the moving tracks is :
- Some wood glue
- 4x little zipties
- 10x Ø3mm 30mm long screws (two nuts per screw) ,
- 18x Ø3mm 20mm long screws (two nuts per screw) ,
- 4x Ø3mm 10mm long screws (one nut per screw)
- 60 nuts for total.
The material you need for the easy tracks is just some wood glue and 4x zipties (again) and 6x 40mm long screws with 6 nuts.
Step 1: The Gun
Step 2: The Frame
Step 3: The Sheets
Step 4: The Hinges & the Trapdoors
Step 5: The Exhaust Pipe & the Random Backside Decorative Box
Step 6: The Sides
You have the choice between two parts if you want to display the Balkenkreuz (the Wehrmacht cross) or not.
Step 7: The Frame Details
You can add the side driver's hatch, the two front armors and the rod on the front hatch.
Step 8: The Easy Tracks
If you don't want to make the moving tracks, there are these easier-to-make tracks. Just stack the 7 slices and add some additionnal rings to keep the track 3mm spaced away from the side part before screwing it (see photos) .
Step 9: The Moving Tracks (Pt. 1) - the Wheels
If you read this, you want to decided to make real moving wheels. Noice.
Be careful to align all the wheels slices.
For the drive wheel : The two geared slices must be perfectly aligned. You can wrap your wheel with your track or, like i did, level the two gears with the table.
For the top wheels : Watch out, the middle slice is very thin.
For the bottom and the rear wheel : Align the holes.
Step 10: The Moving Tracks (Pt. 2) - the Tracks
You will need a lot of patience during this step.
You will firstly need to join all the teeth with the hole-parts and all the hinges with the long rectangle ones (i don't know how to describe them). It will be easier to assemble the whole track with these already assembled parts.
My tracks is 33 hinges long, to give the idea of the total track length.
Just follow the photos for the pattern.
Step 11: The Tools
These are designed by caractere. Go watch his things : https://www.thingiverse.com/caractere/designs
Step 12: The Final Assembly
Fix 4 bolts with the zipties inside the frame. You can now put the side parts with four 10mm screws.

What sized cutting bed do I need on my laser cutter? Or what sized wood panels do I need to cut all of this out?
3mm thick indeed. However, i don't know this .dtd format
i think i used 3 or 4 sheets of 30x60 cm for this one
Were they 3mm thick? Also, do you know how to convert a .dxf file to a 2D Design V2 file (.dtd)?
Or how did you cut it? Did you directly use a .dxf file and send it to the cutter or did you have to first tweak the cut (like the red lines). Are the engrave lines and cut lines already implemented in the .dxf files? Sorry, I'm new to laser cutting
