Today I made a #cyanotype formula dispenser for the standard 3" foam #brush size. I used a previous version of it and it kicked butt. No more wasted #formula. It's a #3Dprinted part made in #freecad. Unfortunately I had to use #chitubox to make the slice file. But the program ran on #ubuntu #Linux so what the heck. I just don't like the incursion of closed source programs into #opensource. I wish someone would please make an open source slicer....how hard could it be...right? Use STEP format plz
