The Capmaster – The Ultimate Bottle Opener for Makers & 3D Printing Fans

Intro

The CapMaster is not just another bottle opener — it’s the ultimate opener for makers, tinkerers, and 3D printing enthusiasts. Designed specifically for people who love smart, minimal, and functional tools, this opener combines simplicity, durability, and fun in one compact print.

Inspired by the classic lighter bottle-opening technique, the CapMaster lets you open bottles quickly and effortlessly — but in a much safer way, without damaging lighters, hurting your fingers, or risking broken glass. Perfect for workshops, maker spaces, BBQs, or relaxed evenings after a successful print.

If you’re into 3D printing, this is one of those prints you’ll actually use again and again.

How to Use the CapMaster:

Using the CapMaster is simple and intuitive:

1. Place the CapMaster under the bottle cap, resting it against the rim of the bottle

2. Hold the bottle firmly

3. Apply gentle leverage upward, similar to opening a bottle with a lighter

4. The cap pops off smoothly — no force, no damage, no risk

Unlike using a lighter, this method is much safer, won’t destroy everyday objects, and is designed specifically to handle the stress of opening bottles.

Recommended print settings

• The text on the capmaster should face down to the print bed

• Nozzle: 0.4

• Layers: 0.2

• Infill: 100%

• I recommend to use PETG because it is a little bit softer, but PLA also works
