I’m going on a fishing trip to Baja, Mexico. Don’t want to get those cold beers mixed up, so I made personalized beer bottle holders for my fishing buddies to commemorate the trip. I used the Brumate Hopsulator Bott’l - the only brand of stainless steel koozie I could find that fits beer bottles.
Lacking the ability to attach a 4th axis to the Shapeoko, I’ve always avoided etching cylindrical objects, but then it dawned on me that I can still do it if I keep the words and graphics fairly narrow and orient them vertically, so as not to defocus the laser too much on the curves. The rows of fish and words are 1/2" wide. The name is 5/8" wide.
I used a JTECH 7W laser and Lightburn on my Shapeoko 3XL. I sacrificed a bottle cooler to figure out optimum settings to etch the powder coat. Settings were:
- 50 ipm
- 100% power
- .002" line interval
- Crosshatch enabled (makes one pass, then another pass perpendicular to the first).
I looked for a free, “fun” font and settled on “Bubble Rainbow”.
Not as fast as a CO2 laser by a longshot, but it gets the job done and I’m super happy with the result.
