Neje Laser Engraver Barrel Etching Jig

thingiverse

I make handturned pens for a hobby and love being able to print someones name etc along the barrel however if you want to print an image or words around the barrel an additional jig is required. I have designed these guides to keep the pen mandrel in place while allowing it to rotate. The guides have longer sides than are required for etching pens because it is a work in progress. As im currently working on an drive roller for the mandrel to allow me to etch rings. Update to follow. Required equipement: NEJE Mini Laser Engraver 3d Printed Part Painters Tape Pen mandrel 7mm Locking collet Procedure: Slide pen blnak and bushings on to the madrel Centralise X & Y Axis using the knob and aligning the guides Add tape to fix the Bushings to the mandrel and the blank to the bushings Add elastic bands to the mandrel Place mandrel between guides Fine adjust x postition by turning the knob on the mandrel Tighten retaining collet Loop elastic bands around build plate Focus laser Double check roller motion by clicking send to machine If roller isnt moving freely loosen either knob or collet Start Etch I designed this thing in Fusion 360 and printed tests in ABS on a MK1 Wanhao Duplicator not the newsest of machines however it should print equally well in pla on newr printers. Hope you enjoy etching those pens!
