Bee-bot cart

thingiverse

I owe the idea to someone else entirely. You can easily find the Bee-bot cart online with a simple Google search, where it's available for purchase pre-made. Since I was in a rush to get my hands on one of these carts for a kids' robotics project, I decided to design and print one myself using Solidworks and PLA material. I've included two versions of the cart - big and small. Personally, I prefer the bigger cart. I've also designed the cart with two different wheel sizes in mind. The 18mm wheels fit better on the smaller cart, while I recommend using 22mm wheels for the larger cart. The cart is specifically designed to work with a 4mm threaded rod, but you may need to enlarge the hole on both the cart and the wheels using a 4mm drill bit, depending on your printer's accuracy and settings.
