IKEA Lack Cable transit 16mm (Table top penetration)
thingiverse
I'm adding yet another cable transit through the top of a Lack table or any other deck around 50mm thick. I've mounted my Anet A6 on a Lack enclosure and wanted to mount the PSU and Raspberry Pi externally to protect them from heat. I designed this to allow a USB lead and two pairs of 12 Volt twin cables to pass through safely. There are two versions available. The initial design had a 16mm internal bore, but I found the back-nut became a bit unsightly due to the thickness of the threaded wall so I reduced the internal bore to 15mm which helps greatly. Unfortunately, some USB printer plugs have thicker casings that won't fit through the 15mm tube, so I've uploaded both versions in case you have similar issues. The penetration will accommodate deck thickness from 50mm to around 60mm, leaving about 5mm of thread biting for a secure hold. I used a 25mm Forstner bit to ensure a clean cut in the cardboard that Scandinavians call furniture. There's only 2.5mm of bezel to cover any raggedness, so take time to cut the hole neatly. Hopefully, someone will find this useful. Update: On May 29th, I've remodeled a set with 35mm flanges to give a bit more tolerance for ragged holes. Update: On August 6th, I added a 40mm version of the tube to suit IKEA Platsa modular systems.
