Keep it simple I say, because I cant design anything complicated. Loving 3D printing, because you can touch your failures and successes, sometimes can produce even something usefull. Trying hard to learn 3D modeling with Fusion 360.
Some of my designs are funtional and have something to do wit accessibility. Im an C5 quadriplegic, so every day solutions are playing big part of my brainfarts.
In Finland you can buy these designs pre printed from HJ Visions webshop:
