Added to the sidebar links on this blog, the free MeshMolder. A new 2020 64-bit version has just been released, in a fairly fully-featured freeware version, and also a $5-by-PayPal Professional version. It’s perpetual desktop software for Windows. A quick test shows there are a lot of ‘Professional version only’ alerts on using the freeware version, but at a mere $5 it’s easy enough to unlock.
Update: Meshmolder 2024 Pro, now available. Freeware in the 2022 version or $6 for the latest Pro.
