The OpenBuilds ACRO System was developed to be the most accurate and cost effective positioning system in its class. The ACRO System incorporates the OpenBuilds V-Slot system and, therefore, has the unique ability to expand to multiple sizes creating a size configuration custom to your needs. Choose the size that best fits your workshop. This versatile system allows for precise positioning of many different mountable tools and attachments.

Realisation of my idea about a foldable collector for rainwater, which is light and easy to make. People around the world need water and can collect rain water with this collector. I made it for syria and all too.

This build will use 1/2 inch copper water pipe as the primary material for all structural parts. As of now my intent is a cartesian design drawing from a few popular printers. I'm going to use the least amount of printed parts as possible and locally source as much as I can. I have built an EMT-conduit core-xy printer in the past and while it worked out fine, I feel copper is easier to work, manufactured with more precision, still reasonably inexpensive and will look super cool!
