I'm posting rails and attachments for my son's Cold Steel Big Bore blowgun. The first piece is a double-sided NATO Accessory Rail ( STANAG 4694 ).
The rails were created using an OpenJSCAD port of the OpenSCAD code from https://www.thingiverse.com/thing:2801254
More parts to come!
For the rails, turned it 90 degrees to put the wider side block down and the split in the tube at the top. I needed to increase the overhang threshold to 60 degrees so the rails would be properly supported during the early stages of printing. There may be a better way to this print, more testing needed.
