Two print “orders” from a friend for his robots

  By

After using my printer to improve my own robots, I quickly peaked the interest of a friend of mine that I know from the LetsRobot Community. He wanted to replace 4 wheels of one of his robots, as well as have a customized mount for his RasPi camera module + LED matrix. As Wheels he wanted to use the open source wheels provided by the LetsRobot team, so that was easy enough. Just download the .stl, tweak a few settings and let it print. Each wheel took a bit over 3 hours and quite a lot of material.

The camera bracket was quick to print, but we needed to design that first so it could fit his needs. Fortunately this wasn’t all too complicated and after finding specsheets for the two modules I could quickly model the bracket for his need.

My first print didn’t turn out too well, and I realized I needed to print it in another orientation. The camera module didn’t fit anyway since I didn’t give the model a big enough tolerance to compensate the quality of my printer. But already the second attempt worked out way better, so I printed the bracket three times (2x for his robots and 1x in case anything breaks) and included it in the shipment.

Cardbot V2 stabilization with 3D Printing!

Once I got my 3D Printer working and had it dialed in, I wanted to do this overdue upgrade. Over time the tape got loose over and over and the motors started sagging so hard, that the cardboard dragged on the ground. This was one of my first designs I created and printed.

These two prints made the bot usable again since it fixed the dragging body as well as stopped the Camera head from constantly falling down.

 

Assembling the Anet A8

  By

Initially I ordered the Anet A8 on Banggood, but it got stopped by the customs office. It did not meet the necessary conditions for import and got sent back to china. It took me 2 weeks to get my money back as well… That was not really a good experience.

The second time i ordered it from ebay – that arrived in just 3 days. All the security upgrades I planned before first use arrived long before that since I waited on the first ordered for quite some time already.

Even before I started up the printer the first time I already upgraded the power supply and added a mosfet for the heatbed. That should rule out the major risks that come with using this cheap chinese knock off.
