As of right now, I am tidying up files and making a how-to document. Will be released soon. I may need to print another one of these to make sure a recent revision works but i am certain that it will. I will include the mini Boomtube in the files. Thanks to Alphacuremom69 for the original Boomtube design. Ask me anything, i am open to questions.
Edit: I will be selling hardware/ rails kits for these. I am contemplating polishing these parts for everyone instead of only deburring, would this be something people are interested in? The rails work much smoother with a nice polish and bevel on them.
What’s the toothed profile you used? Off the shelf?
I used 14.5 pressure angle 48 gear pitch for the profile. Less tooth protrusion and more teeth mean better meshing and stronger rails (less material removed).
