Accu-Nub PCAR Classic- Digital .STL Files – Toy Foam Dart Blaster Accessory

50% Rifling, 50% collet, 100% 3D Printed. No strings attached.

These are the digital .STL files to 3D print the Accu-Nub PCAR. The Accu-Nub PCAR is a fully 3D printed rifled muzzle for foam dart blasters. The “Tetra-Twist” rifling combines 4 constant points of contact to center darts and apply spin to them as they leave the barrel of a blaster, improving accuracy, with a shortened contact area to reduce unnecessary fps loss. A rock solid OFD style printed collet keeps the Accu-Nub firmly gripping the barrel so you can play without any fear of your muzzle falling off. It can be installed on any standard ~5/8ths (16mm) inch OD (or 17/32nds inch OD brass) barrel with as little as 1.4″ of exposed barrel.

EASY INSTALLATION:
1. Place the Collet over the end of the barrel with the threads facing away from the blaster
2. Insert the collet insert for your barrel type with the “long” side facing the end of the barrel
3. Place the Accu-Nub on the end of the barrel.
4. Screw the Collet and Accu-Nub together, keeping the Accu-Nub seated against the end of the barrel as you do so. The collet will compress the collet insert to grip the barrel and prevent the Accu-Nub from sliding or falling off.

PRINTING INSTRUCTIONS:
I recommend printing at a standard 0.2mm layer height or smaller. No supports necessary. Files should be oriented for proper printing (threads up, and collet insert “short side” up).
