multiboard meets ikea kallax

non-intrusive side panels for extra storage everywhere

Posted on January 18, 2026

After setting up a Multiboard tool wall in the server room, I wanted to extend the system to other spots around the office. The IKEA Kallax shelves were an obvious target — plenty of flat side panels going to waste. [Read More]

from gridfinity drawers to a multiboard tool wall

when stacked bins stop making sense

Posted on January 12, 2026

I was deep into Gridfinity for a while. It made sense — I had drawers available and didn’t want to commit to a permanent tool wall in the office that I might regret later. But as my tool collection grew, the drawers became multi-layered and finding anything quickly turned into... [Read More]

motorizing the eibos cyclops

adding a drive mechanism and smart control to the filament dryer

Posted on November 11, 2025

The Eibos Cyclops is a solid filament dryer, but it has a known issue — the stock design lacks a proper heat shield, and the spools don’t rotate during drying. This means filament closest to the heating element gets more heat than the rest, leading to uneven drying and potential... [Read More]

shelly modules on a din rail

moving shellys out of power plugs and into the electrical panel

Posted on October 25, 2025

I got tired of cramming Shelly Plus 1PM modules inside power plugs. They barely fit, they’re a pain to service, and stuffing them in a sealed enclosure raises heat dissipation concerns — not ideal for something switching mains voltage. [Read More]

new guts for the home server — ready for vms

Posted on October 19, 2025

My home Unraid server was getting cramped and slow, mainly because of all the containers I had been using and the amount of new workflows I’m pushing to it. With even more coming up and the need to start using VMs alongside the docker containers, the old hardware just wasn’t... [Read More]

speeding up multi-color prints with the ams speeder

shorter filament path, faster color swaps

Posted on October 14, 2025

The default AMS setup on the Bambu Lab P1S routes the PTFE tubes from the AMS, around the back of the printer, and into the filament hub — a long path that adds up on every single filament swap. On multi-color prints with hundreds of color changes, those extra seconds... [Read More]

inline smart power cable

non-intrusive smart power control for 3d printers

Posted on October 13, 2025

I wanted to remotely turn my Bambu Lab P1S printers on and off via Wi-Fi and track energy usage — without opening or modifying the printers. [Read More]

moving the printers next to the server rack

a dedicated room for noise, heat, and fumes

Posted on October 8, 2025

The two P1S printers were originally sitting in the open, next to the filament storage. It worked, but the noise during long prints was annoying and there was no way to manage fumes — ruling out more abrasive materials like ASA or ABS. [Read More]
