This is an idea inspired from our constant need to swivel our IKEA Tertial Lamps around to reach different areas of our workspace.
The problem arose from the fact that the lamp base was designed to hold the lamp in a stationary position and was ill-suited to swivel easily. With the weight of the lamp (especially when fully extended), the weight and the angle tends to gradually wear down the lamp base. Hence, there are several 3d printable options for a replacement lamp base on sites like Thingiverse:
Now, while these work fine for folks who are looking to replace their worn out mounts from their stationary IKEA Tertial lamps, it still makes it a sub-standard way for our use in the studio where we value the swivel-bility of the lamp.
Working towards the Solution
At the same time, we had a couple set of 608z bearings (formerly used for skateboards and fidget spinners) lying around. Putting both together, we decided to scratch our own itch and come up with a more robust design which would be an improved design for a swivel base for our Tertial lamps!
The upper swivel portion is of a simple U clamp design where the metal peg end of Tertial lamp can fit in from the top, supported by the 2 extruded arms on either side. The 608z bearings are then snuggly fitted in from the bottom, to be centered upon the inner cylindrical peg from the bottom.
To be able to better spread the stress, the final version allows for two bearings to be added instead of simply one.
Here’s a simple exploding animation to show how the entire assembly comes together:
3d Printing and Assembling
With these 3d designs all completed in Fusion 360 – it was time to get them ready to be 3d printed. Slicing is up first:
At this point, it’s important to remember to bump up some 3d print settings (for both parts) to achieve a more sturdy and robust 3d printed part:
- Layer Heigh: ~0.2mm
- Infill: ~30%
- Number of Shells = 3 or 4 shells
And here’s the top swivel getting 3d printed out on our ATOM 2.0 3D Printer:
After which, the two 608z bearings will need to be snug-fit into the underside of the Swivel Top:
Last bit would be to clamp the base portion to the table, affix the lamp onto the swivel top and put both halves together, and here it is in action!
