Ikea Tertial Base w/bearings

thingiverse

Finally a sturdy base for the Ikea Tertial lamp that actually works! I created a similar design 1 year ago, but it had some major flaws. Here are the problems I encountered: 1. The bearings made it so smooth that if the surface wasn't perfectly level, the lamp would freely fall and rotate towards the lowest point. 2. Because of the high lever at the base, some layers split. I finally solved these issues! To prevent the lamp from free rotating due to gravity, I implemented a brake system. My first idea was an aluminum indexing plate with a ball plunger, but then I decided on a more simple friction brake (both adjustable). I ended up going with my original idea, but I think the friction system will be more durable and it's easier to make - no need for a CNC machine, just a 3D printer. I'm sharing both options, just in case. To fix the layer splitting issue, I used more screws not only to hold the lid and internals, but also as reinforcement of the entire base, giving them full length. Here is the BOM: 1x Base (3d printed) 1x Lid (3d printed) 1x Smooth_plate (3d printed recommended) or 1x Index_plate (CNC) 1x Lock collar with set screw (for 8mm rod) 1x 8mm steel smooth rod (I used M8 thread rod) 2x 608 bearings 1x M5 locking nut 1x M5x12mm ball plunger (a set screw will work on the friction plate) 8x M3x35mm socket head screw 8x M8 nut Check out the pictures to see how I glued the rod with metal epoxy to the end of the lamp and the friction plate to the lock collar.
