BF001: Completed printed buffer

We offer to produce and supply the complete RMU-Mk3. The total print time is nearly three days which some people may find onerous. The complete kit comes supplied with all the fittings pre-assembled so all you have to do is attach the top, base and the brackets and Teflon tubes.


You will receive all the component parts of the RMU-Mk3 plus a bill of materials, links to assembly instructions, tips and tricks and any other resources we think you might find useful.
