This is something I had to post a long time ago, the openbuilds site is a community site for makers where you can publish your open projects.
The site is created by the nice people of the openbuildspart store, the same people who launched the V-slot aluminium profile. ( I backed their Kickstarter V-slot campaign and have some of the first few meters of 20 x 20aluminium profile).
If you are searching for a Delta 3D rpinter design or a portal cnc router, then you’ll find some nice design over here.
Next step is buying the parts at their store, really fair prizes for decent material. http://openbuildspartstore.com/
They have some dealers over here in Europe like https://www.iprototype.nl/search?search_string=v-slot
My goal is to make a portable cnc router and/or 3D printer with the v-slot profiles I obtained, I have already a 3D printer and 2 CNC routers, but the v-slot profile can make very compact designs and that’s what I need.
So happy building.
