Planning on using this bot in your (first) battle? You might want to consider wearing the appropriate clothing for the occasion: https://teespring.com/nl/antweight-battlebot-bulldog?pid=389&cid=100029
I was thinking about building one for a long time and finally started the design, bought the necessary components and put it together. I'm quite happy with the result so far. However, this bot has never fought so i don't know exactly how well it will perform in an actual game. The 3D-printed blade is great and the aluminium one is even better but i'm not sure how well the 3D-printed armor will hold up. I think this bot might be best suitable for games where only fully 3D-printed bots are allowed.
The total weight of the bot comes in at around 144 grams and it fits within a 444 inch (101101101 mm) box, not flat but this isn't a requirement.

The reason I gave the bot the name "Bulldog" is because Bulldog ants or one of deadliest ant spieces in the world ;-) https://lakenormanpest.com/top-8-dangerous-ants-time/
Thank you to Flsun for providing me with their Q5 3D-printer. At first I was very sceptical about delta 3D-printers because i had bad experiences with them in the past. Delta printers are usually hard to set up and level because of their complex kinematics model. I didn't have any of these problems with the Q5 and this is my honest opinion. I think this is one of the best (if not the best) 3D-printer for absolute beginners.
