The filament storage box was now in a state that I could start wiring everything up. Running the wires was pretty quick, but then I had some software work to do before things started functioning. I had stubbed out a lot of the code back when I assembled the circuit board, but there’s only so …
Coming up on the end of fiberglass work, I completed the first layup for the box cover, the outside. This was pretty easy since it’s mostly just flat, but the glass has to go around the edges and conform to the corners. The cloth will go around a 90-degree corner but only barely. Since the …
With the bottom of the box done, time to cover the remaining bare foam on the front. The front is 1.75″-2″ wide so we’re talking applying glass tapes all around. To bond to the sides a loooong flox corner was needed all around the inside and outside, which required a lot of Dremel work to …
Now it’s time to complete the bottom of the box, fitting the penetration bracket into it. First, the shape of the bracket was measured out on the bottom of the box, and the foam removed to the depth that would match the bracket using the Dremel. This recess was then beveled to match the bracket. …
It’s been a couple of weeks since the top of the filament storage box was completed. In the time since, I’ve been working on the bottom. The first thing that had to be done was to add a drain for the water from the dehumidifier. I did this by adding an aluminum hardpoint glued to …
With the sides of the box completed, it was time to glass the top. The layup itself was pretty straightforward, since it’s just a flat piece of glass that laps onto the sides and back. I added aluminum hardpoints for the screws that will hold the electronics enclosure and another hardpoint that can be used …
Since the last filament storage post, the storage tube assembly was microed into place. I covered the foam around the hole with duct tape to prevent getting micro on the foam surface, and poured slurry into the holes. The idea was to get enough slurry into the holes that it just filled all the empty …
The work on the filament storage box has lately focused on what to do with the filament tubes when they’re not used. The box will fit up to 8 1kg rolls of filament (or 4 3.5kg rolls), and those filaments will exit the box in PTFE tubing through the bottom of the box so they …
After 4 sides of the box were assembled, it was just the top left. This should have been quick but was delayed by the need to first bond the bracket that will hold the circulation fan to the inside surface. Had I designed the box today, with the intent to use the bed heater, I …
After starting to assemble the filament storage box, I was distracted by the house fumigation and repairing the Flightradar24 antenna, but this weekend I finally had time to apply the corner tapes to the inside corners. This is pretty simple, the idea is to apply a strip of fiberglass cloth to join the two sides …
