For anyone who hasn't eaten a real one of these, I can assure you that a 3D printed version would taste better.

Ding ding ding! I think we have a winner. I CADed exactly the same thing without the exterior details.

Is there any reason for the spikey exterior, or just for fun?

The reason we have the spikes is because we were worried about the grip of the bands on the spacers. We plan on spinning the rollers fairly fast and also we plan on powering multiple rollers with just one motor so the grip of the bands on the spacers is extremely important if we want a working bot.

If you want the STL file for this part you could pm me and ill try to get it back to you as soon as i can.

Thank you for this! We have been struggling with our flat belts - this may help.

By the way, we have been mining your previous robots for some time! We may have found another answer if you want to pm me!

Not sure what width flat belt you are using, but 1.625" Baby Colsons work nicely as crown pulleys for 1" flat. Lots of grip on the belt as well.

Some years ago, I was on vacation with the family in Asia, and I walked into the hotel room to a horrible smell coming from the closed door of the bathroom. Multiple scenarios came to mind including sewer backups, clogged toilets. I opened the door to discover my parents hiding inside, sheepishly munching away on durians.
