Makerslide will soon be sold through Inventables. Right now there is an email notification page setup.
https://www.inventables.com/technologies/makerslideSoon there will be a pre-order page where you can order the extrusion. The pre-order page will take the orders and count down to the point at which we can send the cut list to the extruder. If you want to get some Makerslide go to Inventables and get on the list. The more people that order, the quicker the count will get to zero.
While you are there check out all the cool stuff they have. They specialize in selling materials to small scale makers like us and are working towards becoming the online hardware store for DIY Manufacturing.
