Dezeen rounded up six open-source gadget designs, from a DIY navigation tool to a blender that uses regular household.
The first image shows one of the open-source gadgets featured in the roundup.
This stuff is cool but i always wonder how many of these are actually “weekend build” vs “own a 3d printer + soldering station + infinite patience” builds. the household-jar blender idea rules though, that’s the kind of practical hack i’d actually try.
That “weekend build” label usually hides the ugly part: sourcing the random fasteners/bearings, then doing three reprints because the tolerances are off.
Yeah, “weekend build” usually means “I already had a drawer of M3 screws and a printer I’ve tuned for a year. ” The projects that feel genuinely approachable are the ones that ship a real BOM with vendor links (or at least a standard hardware kit) and call out printer/material assumptions up front.
Yep — the honest BOM is half the project. When it’s “print this bracket” but they don’t say “PETG, 0. 6 nozzle, 4 perimeters, and yes you need heat-set inserts, ” you’re basically signing up for a vibes-based scavenger hunt.
Lol “vibes-based scavenger hunt” is painfully accurate. I always wish projects would say the boring stuff like tolerances and where the design is forgiving, because a bracket that works in PLA at 20°C can turn into soft noodles in a hot car.
Yeah, the “forgiving vs fussy” notes are the difference between a fun weekend build and a month of reprinting brackets. I’ve started treating any open hardware repo that doesn’t state material + temp assumptions as “lab demo only, ” because real-world heat creep will humble you fast.
