+====== 2022-09-16 - chair repair ======
+yesterday my son swung on an arm support of my chair... and broke off 1 of 2 holding screws.
+since i work from home it required immediate attention. :)
+after disassembling the chair, it became clear that a metal, welded part broke off.
+"blue" marks the still-holding mount, while "red" is a missing one.
+{{:blog:2022:09:16:chair.jpg?400|disassembled chair}}
+the chair is old (15+ years), but perfectly functional.
+i.e. one, small part breaking off should not be the show stopper.
+after giving it a bit though i decided to use 8mm threaded rod as a replacement for load-bearing rod from the original mount and a [[https://github.com/el-bart/mini/tree/master/chair_repairs|3D printed replacement harness]].

+after printing (PLA) and assembly it it fit perfectly.
+{{:blog:2022:09:16:new_mount.jpg?400|new mount in its final location}}
+after assembling back the chair i honestly cannot tell a difference!
+the whole repair, end to end, took me around 2.5h.
+out of this time around 1h20m was printing time and around 40min measuring and modeling.
+some ppl complain that 3D printing is just creating plastic waste as ppl just print more Yoda statues.
+i'd argue that's not the case - at least not in general.
+with 3D printing you can easily produce replacement parts or create brand new things.
+killer-app for 3D printing -- perfectly-fitting enclosures for custom electronics. :)
+w/o 3D printing i would not be able to repair the chair easily.
+the part that broke of was a custom-made, hand-welded (trust me - you can tell ;)) thing.
+there's no way i could get a new one for 15+ years old chair, even if i still remember manufacture's name. ;)
+sure -- i could cut-and weld new one, but living in a flat, i do not have an easy access to tools required.
+with modern technologies however i was able to fix it on the spot.
+we live in great times! :)
