Big progress today: the epoxy glue finally arrived, and I picked up a budget-friendly table saw from the local hardware store. The old method did the job, but hey, a little extra comfort never hurts. Since I can’t resist inventing little tricks to make life easier, I also designed a small jig. The jig’s mission: to taper the 40 mm bamboo tubes at their ends. It works in neat 2.5 mm steps, shaving off just enough material at a time. That way I can use both hands while working—more control, more safety. Right now, the printer is busy cranking it out. Fingers crossed that everything fits perfectly. With a bit of luck, I’ll have something to show tomorrow! 🔧✨ ...

Today felt like a real kickstart. 🚀 I ordered some epoxy to firmly bond the lugs to the bamboo. This is the backbone of the project—without solid joints, there’s no bike. I’ll probably need to dive deeper into the world of resins—there must be tougher ones out there to make the frame even stiffer and stronger. To be continued! Another milestone: the first draft of the bottom bracket is drawn. It doesn’t look like much yet—basically a skeleton version with just the bare minimum material needed. But it exists now, and it’s ready to be printed. That’s already a win. ...

Today was all about getting organized. We ordered a sample bike (arriving next week) and a bottom bracket adapter (arriving tomorrow). Which means: perfect moment to set up a proper task list. And since there’s nothing secret about it, why not make the task list public? Fun for whoever happens to be lurking. 😏 So I figured: let’s publish the list straight from Obsidian to Hugo, Kanban-style. To do that, I built a shortcode that converts Obsidian markdown into Hugo-ready HTML with Kanban formatting. Not sure if someone already did this, but just in case, here’s the gist of how: ...

Not every day can be a productivity marathon, and that’s perfectly fine. Today I had to take care of some other things. Still, I managed to squeeze in a project task: adding a protective coat to the sample I printed over the weekend. This lug — printed with 100% infill — is seriously tough. Pretty promising, right? Reflection Not every day has to be a productivity sprint. Taking it slow can be just as important. As the saying goes: “Rest is also progress.” ...

The past two weeks went by faster than a sprint finish! Time for a pit stop: plenty of progress has been made, though the ultimate goal — a 3D-printed frame with bamboo tubes — is still on the horizon. First up: a design sprint where I drew all the lugs. The first print? A flop. But honestly, that failure was the best teacher. It pushed me to try a new approach: milling the tubes so they slot neatly into the lugs. That way, the bamboo’s outer diameter lines up nicely with the 3D-printed parts. Will it be strong enough? We’ll find out soon. ...

Your browser does not support the video tag. Note to self: if a print pops loose… just slap on a brim and try a different orientation. Easy fix, lesson learned. ✅ Next, I cooked up a set of rigs for the very first lug. These are my secret weapons for filing the bamboo tubes down to the perfect diameter. The big rig clamps right into the vise (yep, totally over-engineered… but that’s how I roll 💪). The smaller ones slide over the tube with a 1 mm tolerance so I can mark the exact circle I need to file. And the hole at the bottom? That’s the final boss. If the tube slips through, I know I’ve shaved off just enough material. ...

🚀 Carbon-Fiber Filaments: The Turbo Upgrade for 3D Printing Sprinkle chopped carbon fibers into your usual plastics, and suddenly you’ve got superhero materials: stiffer, lighter, and way less prone to warping. But beware—CF filaments are not all equal. Some happily run on hobby printers, others demand a machine that’s basically a small furnace. Here’s the cheat sheet: the most common carbon-fiber filaments, with specs, perks, pitfalls, and best use cases. ...

Today wasn’t exactly a productivity powerhouse. Probably not the most exciting devlog entry either, but consistency matters — so here we are. The morning was spent measuring stuff for another project (details skipped for now). After that, I rushed to the office to get back to this project. Just for fun — and aesthetics — I’ve started painting one of the parts. First step: filler + sanding. One round down, many more to go until things are nice and smooth. I’m still undecided if painting is the way to go, since it adds a ton of extra work when building a frame. But hey, it’s worth a shot. One lug in particular has a pretty gnarly overhang, and filling it makes the layers way less visible. Next up: I want to reprint the last model so I have a second sample to work on. Today’s goal is making small tweaks and preparing for that. ...

A Surprising Start New day at the office, new surprise. Even though I had already spotted it on the Live Feed, it was still a bit of a shock to see the printer in the morning: the print had shifted halfway through. Frustrating, since an error like this means hours of work down the drain. What Is Model Shifting? Model shifting in 3D printing happens when the layers no longer line up, leaving a visible step or offset in the object. Common causes include: ...
