Printed a lid for my titanium camping mug - 9g, vase mode, FreeCAD revolve

My Forclaz 400ml titanium mug fits a BRS stove, lighter, and 100ml gas canister

inside but has no lid. So I designed and printed one.

Print details:

- Printer: Ender 5

- Material: PLA

- Layer height: 0.2mm

- Mode: spiral/vase (single wall shell)

- Print time: 41 minutes

- Weight: 9g

Designed in FreeCAD 1.1.1 - sketch on XZ plane, revolved around Z, grip grooves

are sphere Boolean subtracts with a polar pattern x5.

Fit took a couple of tries - inner diameter is 91.6mm and the rim lip is 1.5mm

radius, pretty tight tolerance for PLA.
