@jubei @504DR @gerrymcgovern A *very* unsophisticated search for shark vacuum brought up these parts for #3dPrinting printables.com/model/888803-re

Of course I can’t know if these are anywhere near what you’re looking for.
Either way, there is many parts and accessories available if you have access to a 3d printer.
printables.com/search/models?q

A more elaborate search is likely to yield better results. Or design your own spare parts and share.

My custom version of a painter's point. I have a bunch of the traditional ones, and they work great for panels and wider workpieces, but are almost useless for narrow workpieces.

When I was making my grandson's crib, I took a few furring strips and drove a bunch of drywall screws through them pointing upward for finishing the spindles. They work reasonably well, but aren't very flexible.

These should work great for smaller workpieces.

In the center of the frame is a painter's point made from white PLA roughly in the shape of a square pyramid hollowed out. Each side is composed of an M-shaped truss with the corner upright shared between two sides, creating a point at each corner. Thus, rather than a traditional painter's point with a single point, this version has 4 points. I'm sure I've botched this description badly, but it's a difficult thing to describe.

I don’t have a 3D scanner but I want to 3D scan something.

What’s the recommendation in the year two thousand and twenty five?

Photogrammetry with meshlab? Lidar scan with my phone?

I have a light box and a motorized turntable if that is useful.

Anyone east of Seattle have equipment they want to share?

As I swapped out the winter tyres for summer ones today, I checked out the hubcaps I made last fall and they all were in perfect shape.

I replaced my pinball hauling vehicle last fall and I had gotten used to the Volkswagen T5's minimalistic hub caps. Ford Transit had had those at some point but all that was sold these days was beaten up ones for very high price on eBay.

So I recreated the hubcaps in FreeCAD and printed them out of ASA. They're soft enough to snap on without violence, but they also stick on just as well as the Volkswagen version. I stole the wheel bolt attaching design from them.

@sheddi @pluralistic I think there'd be quite a market for retrofits of this sort: open hardware appliance controllers running open-source software, to rip and replace the stock controllers. Ask #lawfedi to be sure, but I'm pretty sure it doesn't count as DRM circumvention to remove and discard the DRM-containing electronics and install de novo replacements.

I imagine the retrofit kits could be sold either as boxed kits or pre-assembled, like @frameworkcomputer products.

I imagine there'd also be a significant secondary market for installation services, and perhaps also for retrofit design: reverse engineering non-computerized wiring; scanning and quantitatively modelling appliance cavity geometries; designing compatible adapter circuits between a PLC, programmable microcontroller, or SBC and the operational hardware (e.g., motors, fans, and heaters or compressors).

And I imagine there'd be a need for an (ideally federated) community repository of retrofit spec files: detailed internal physical dimensions of cavities in appliances with their stock controllers removed; wiring diagrams and documentation of residual non-computerized electronics; connector specifications (e.g. which type of wire end to use); instructions like on @iFixit for opening, removing stock controllers, installing replacements, and closing; and #3Dprinting files for controller mounting brackets and the like. This would best be community funded like most of the rest of the #fediverse.

I imagine there'd also be room to community fund development of firmware or software for the replacement controllers.

There could also be a tertiary service market in safety testing and re-certification of retrofit appliances, in case anyone wants to resell their retrofits with insurance and all.

And I second favouring "Unauthorized Bread." Unlike the poor migrants in the book, though, enough of us can currently afford to hack the hardware rather than the firmware, by removing and replacing all but the passive and operational components, discarding and replacing every programmable but not (intentionally) owner-reprogrammable component. Indeed, I'm sure it's best those who can, start working on this immediately, before #GreatDepression2 kicks in.

Due to life *waves around in general* my #3DPrinter has sat unused for possibly six months? Anyway the filament has deteriorated in the Bowden tube and the hot end. This meant I had to dismantle the whole shebang. Then stick the Bowden tube in boiling water to soften the old filament. Anyway. All sorted and the new ‘Fire Engine’ red filament passed the calibration #cat test. #3DPrinting #Ender3

Qidi 'engineering' strikes again: reddit.com/r/3Dprinting/commen

tl;dr - a Qidi Plus4's SSR (which we have been warning about since day freaking 1) finally blew and caught fire, with serious consequences.

I've said it before and I'll say it again: do not buy Qidi printers, don't suggest others buy Qidi printers. This isn't just sloppy engineering, this is outright dangerous.

3D Printing Industry · US researchers develop new bioreactor for enhanced stem cell growth - 3D Printing IndustryResearchers from Los Alamos National Laboratory (LANL) have developed a 3D printed perfusion bioreactor (3D-PBR) created to improve how human bone marrow-derived mesenchymal stem cells (MSCs) grow and differentiate.  With contributions from the University of New Mexico (UNM), the device also supports co-culture with vascular cells. Designed to address the limitations of basic cell culture […]
