The last few years were not that great for many things - including Boxes.py. It's been a while since the last proper log entry. And I have a dozen more that are not much more than the first few lines of code and I am not confident enough to publicly admit here. I have toyed a bit with flexures and thought about doing a laser cut microscope like the OpenFlexure Microscope although with very different kinematic. And I have a half working one for arbitrary sizes. I saw a cube box at the Fablab of the University of Oulu that is cut directly between pieces without creating gaps. I wanted to create a calendar with them, preferably perpetual or even some clever mechanical one. I have a cryptic font that is mostly finished with each letter is just a few shapes that are only legible when surrounded by a border. I just started with a wire straightener holding two rows of v-groove ball bearings. So far my backlog is all but empty and I still have more ideas. So if one brave soul is looking an LED stripe fueled clock project let me know. But I am not sure if I get to build one any time soon. Both of them are still flagged "unstable". The obvious use case is a seven segment clock. So you can create a seven segment display without much soldering or special circuit boards and from semi small to quite big. ![]() The idea is to use a LED stripe on its side and wind it through the seven segments. So if you feel adventurous and "need some Tetris blocks in your life" please donate a few good pictures.Īnother "thing" that I started long ago and started over with more than once is my Seven Segments feature. I am optimistic they fit, but I have not yet cut them out. So the only tricky part was getting the lengths right as we do want the walls to be within the perimeter of the block structure. There also is a companion method to create all the side walls from the same list. Nowadays this is much easier as we have the polygonWall method that gets a list of lengths and angles and handles the rest. At the time this wasn't that easy and quite a bit of work. One generator I started a long time ago was one for generating Tetris blocks. So, I did a spool that can be separated into two parts using the BayonetBox as a basis:Īnd as I was at it it was just too easy not the strip it down to a one piece spool (and then add some fancy reinforcements): May be one day the two above get a fancy sibling.įor another project I need to 3D print a small part (yes, I know, heresy) but the filament didn't come with it's own spool. It is more ambitious with 3 layers on each side that allow locking in the axle by rotating the middle layer. so a "Wall" variant was needed:Īfter finishing both I found another 20% finished holder in my working dir. So I did a roll holder for the kitchen after the old, 3D printed one broke: Funny enough a lot of these new generators come in pairs. ![]() Additionally there where a few needs that popped up that also needed instant addressing. I have been working on getting some of them in shape for inclusion. Is used for rounded edges and living hinges.īeing able to put more time into the project have I looked into my local repository and it is full of half finished projects - most of them new "box" generators. Putting holes and slots for screws (bed bolts) into finger joints,Īlthough this is currently not supported for the available generators.ĭovetail joints can be used to join pieces in the same plane.įlex allows bending and stretching the material in one direction. "thickness" to maintain the same appearance. Their size is scaled up with the material ThisĪllows fine tuning the gaps between joins up to the point where plywoodĬan be press fitted even without any glue.įinger Joints are the work horse of the library. The "burn" parameter compensates for the material removed by the laser. Of the material used and automatically adjusts lengths and width of Of course the library and the generators allow selecting the "thickness"
