Premium Members SergeiFranklin Posted March 21, 2011 Premium Members Report Share Posted March 21, 2011 I have had a Bartech for over 10 years and tried many focus rings. Last year I came across a design from Markus Bernhardt, www.baer-bel.de that I liked but he didn't want to make anymore. I recently discovered www.shapeways.com , a 3-D printing service. I designed rings based on Markus Bernhardt's design with Google SketchUp, converted it in Meshlab and then opened it in Netfabb to finalize size and output a .stl file to upload. These are all free software that can be downloaded. sketchup.google.com meshlab.sourceforge.net www.netfabb.com Mine is here http://www.shapeways.com/model/218566/focusring.html?gid=mg This is for the early Bartech that had a slightly different knob diameter I have 20 rings and there are small variations as some are tighter but all fit. I recommend you order one (wether my design or yours) to test before you order a large number. I am not selling them(I'm not adding a markup), you are ordering from Shapeways. The price with customs is about $20 a ring. If someone designs one for the new diameter or a different design please post it. You should be able to download the design. If it's not working I can send you my file. "Opensource Focus rings" Sergei Franklin www.sergeifranklin.com Quote Link to comment Share on other sites More sharing options...
