Many people have asked me for the stl’s for my printer using connect-it to build a frame. I have been struggling to get the 19mm tubes here while 25mm is easy to find everywhere. I will be putting it together with the larger sizes in the next few days and have order enough of this to have parts for a few extra sets available as I believe its hard to find elsewhere. connect-it is the red squares on the corners. I will build another machine with the bigger sizes and then post the plans with a howto somewhere.
