I wanted to build a wolfstock style delta-bot, using Makerslide linear slides. But, I wanted to run the belt through the inside of the Makerslide for a cleaner look.
This is still very much a work in progress, I'm currently working on completing the design and building the printer.
I'm posting a build log on my blog:
