I started printing bots out of PLA+ which is supposed to be a lot stronger than normal PLA yet prints about the same. So far so good. We can start assembling the final bots now.

Even when I think I’m finished, I’m really not. The lid didn’t fit properly. Well, it was fine except the switch location didn’t fit. (the switch interfered with the motor mount) And, I realized that extruding the “doorstop” at 90 degrees to the plane was wrong. That back point is NOT 90 degrees. It’s a…

I still haven’t drawn the lid. That’s the final piece. Hopefully, after this, everything just fits and I can print a couple out of PLA+.

I added a cavity to accept a 10mm x 2mm magnet. Once the printer started printing the layer which will cover the magnets, I paused it. I placed the magnets in the cavities then pressed continue. This print was a bit over 2 hours. I’m honestly not sure how much these magnets will help. If…

Okay, it may not have been quite as serendipitous as I thought. After adding up all the additional hardware required, I was well over 150g. I managed to lose around 8g today, but I still have about 10g of hardware to add to this pile. It’s going to be tight.

I got 100 magnets in the mail today! 50 are 10mm x 1mm and 50 are 10mm x 2mm. I plan to insert these into 3D prints of robot chassis. I’m not entirely sure how to do that yet.

So I’ve decided to build another antweight bot. (US Ant is 1lb. Not to be confused with UK Ant.) I last did this in 2015. I dug through my bins and found plenty of parts, so decided to try to build with what I have as much as possible. I found a bag of 10…
