Designed these in Fusion 360 with parametric dimensions so I can change angles and thicknesses with a few key strokes. Thanks Fred Wissen these printed with 3mm filament...

I'm not sure how he does it but if was me, I would be using a small funnel either plastic (cleanable) or make some out of craft board (disposable).Those look very nice. How do you pour them? Do you tape off the channels you want to keep clean and do one at a time or are you steady enough to not spill the resin in the wrong hole?
