Moose Head by MorenaP for Materio3D scaled to 100 mm wide and modified to take a NeoPixel Diffused 8mm Through-Hole LED. Use the clearest filament you can find and you've got a rainbow glow moose!
Licensing requirement from creator: if you create a derivative of this, please keep the logo visible somewhere.
(I had to move the Materio3D logo from under the LED void.)
Use the clearest filament you can find. I found that printing solid with radial infill helped with the material I used.
Hard to believe but this model doesn't need supports!
Clear PLA tends to form very fine threads unless you print very slowly and manage retraction extremely carefully. Running a heat gun very quickly (a couple of seconds) over the model makes most of these go away. PLA melts quickly, so keep the heat gun moving.
