I designed this in Solidworks, then gave it texture in Meshmixer. There are two models: The “STL printer” model is intended to have a full raft supporting it, not to be printed directly on the platform. The “FDM printer” model has a flat bottom to print directly on the printer bed. I printed one using Tough resin on a Formlabs Form 2 printer. I printed another on a Prusa MK3S using Prusa space gray PETG at 0.15mm Speed and 5% grid infil.
The author marked this model as their own original creation.
