I’ll be at @opensaucelive.bsky.social this weekend with the Positron Team wearing my Positron Backpack through-out the event. If you spot me please say hi!
I plan on adding base plates to the workbench drawers. The goal is to have all my common fasteners and electronics components sorted so I can quickly prototype and fix stuff. Reducing friction to making stuff is my priority.
My multiboard journey begins... The workbench had a standard pegboard backing but it wasn’t easy to customize so I fell into the multiboard rabbit hole. Its a free modular storage system using 3D printer optimized models. multibuild.io
Open source hardware is awesome. I had a user on Printables make a feature suggestion to add a list of screw angles instead of just opposing sides and I was able to add and test it fairly quickly.
I used the EM3D Scanner App to get a rough mesh in Fusion for a sketch profile I could use to create a form-fitted handle. You use "Create Mesh Section Sketch" then "Fit Curves to Mesh Section" and trace a sketch line to follow the mesh profile. I find 3D scanner reverse engineering is very tedious.
Custom lampshade printed in vase mode. Fairly easy to design with a sketch and revolve pattern. Set extrusion width to 0.6mm with a 0.4mm nozzle. Perfect print with Prusa Core One.
I got a crt monitor that I dragged here when I moved but didn’t know what to do with it. Well I moved the Core One printer to the other side of the shelf and now use the crt as a secondary monitor. 1280x1024@60hz seems to be the sweet spot (even though it could do 1900x1200 somehow).
Type F went together well with Elixir Nightshade. It’s about the minimum scaling I’d want to do with a 0.4mm nozzle. I’d suggest both at maybe 125%
Towel clip for oven handle with curves. Measure the square dimensions, guess the intersection points, and use fit point spline. Perfect fit on first print!
I started this shelf project about 6 months ago when I moved into my apartment. I developed a parametric dowel rod connector system to build it then I had the hardest time motivating myself to finish it. I had to problem solve since I built it with basic tools and my Mk4/Core One printing 6+kg PETG
I saw we're doing 2016 throwbacks. On this day 10 years ago, I was making the first prints on a Mendel 90 we built for the "How to build a RepRap 3D printer" class I taught at the Dallas Makerspace. I would have never guessed I'd be making a living working on 3D printers founded by RepRap today.
I finished building my @prusa3d.com Core One+ from a Mk4. It looks really nice.
Clever @prusa3d.com Core One+ design. With 4 simple PETG printed parts, they were able to redesign the filament switch to disengage the ball detent, which usually restricts TPU. No extra hardware needed.
Finally after 6 months, I hung my reprack. I had to shorten it to 1.5m to fit above my desk. All of this I’ve acquired since I moved here, I guess working at a filament company isn’t too bad. @repkord.bsky.social
I ended up getting a new mobo because the Alienware board complained and this was a cheap upgrade. It has ARGB headers and two M.2 slots. I did some extra wire management so it’s clean. It’s much quieter and cooler than the Alienware aurora case.
I struggled to get this kit out of my car. It’s about 20kg. I think a robot is needed.
