Office Chair (with two remixed parts)

Office Chair (with some remixed Parts) History About 3 years ago a valued teammate goes into retirement. Some of us decided we had to do a farewell present that represents his work. His main duty in our IT division was the backup system. So it was decide we would take a nonfunctional LTO Cartridge, empty it of the tape, paint it in gold and make an inscription panel. Additionally we would require some sort of stand. I volunteered to print one on my, then very new, 3d printer. But non suitable model was found, so I decide I would recreate our teammate’s office chair which was a unique model because of medical problems with his back. I was never good with sanding down, coloring or doing a good finish overall. But this project was teamwork from the beginning. So I build a sort of model kit, gave it to another teammate that did wonders in finishing that thing. Time was of the essence and that chair was my first larger project in 3d printing. So, in the end, I had to download a chair base and the wheels. As I recall the base was mostly scaled, but the wheel mount was additionally modified to hold a pin. The wheels itself needed to be reconstructed to fit. The scale was chosen so that the cartridge could take a seat on the chair. Construction started on 21 of December 2018. Handover of the present was on 29 of January 2019. Printing I printed all parts with 0,1mm layer height. All small parts were printed with 100% infill. Larger Parts can be printed with much lower infill percentage. Most parts can be printed without any supports. Some printers tend to print “inner holes” smaller than constructed. So it might be that the alignment pins will not match. If that is the case scale them down a little bit in your slicer. 1x Chairbase – remixed, needs heavy support 5x Wheelmount – remixed, no support needed 5x Wheelmountpin – no support needed 10x Wheel – no support needed 1x GasSpring – no support needed 1x GasSpringLowerEndCover – no support needed 1x SeatUnderconstruction – no support needed 1x SeatRightPart – no support needed 1x SeatLeftPart – no support needed 1x SeatBackRightPart – no support needed 1x SeatBackLeftPart – no support needed 9x SeatAlignementPin – no support needed 1x LeftArmrestOuterPart – minimal support needed 1x LeftArmrestInnerPart – no support needed 1x RightArmrestOuterPart – minimal support needed 1x RightArmrestInnerPart – no support needed 4x ArmrestAlignementPin – no support needed 2x AdjustmentWheel – no support needed 1x LeftKnob – no support needed 1x RightLeverOuterPart – minimal support needed 1x RightLeverInnerPart – no support needed 1x RightLeverAxisExtension – no support needed 1x Cushion – Flex Material (TPU), minimal infill Assembly The wheelbase unfortunately needs a lot of support and some post processing, like sanding the underside down a bit. As axis I used small parts from a paperclip from our office :-) . Glue one wheel to the axis. When cured, push the axis through the wheel mount and glue the other side on. The wheels should rotate freely. Stick a “wheelmountpin” part in the wheel mount and then the whole assembly in the wheelbase. The wheel mount should be able to pivot around, even when a little bit tight. If the pin is not holding I suggest gluing it to the wheel mount, not to the chair base. Glue the gas spring part into the base. There is a cover to close the underside of the gas spring part. Try out, how the seat underconstruction part fits together with the two seat parts using seven “SeatAlignementPins”. Glue the parts together. Glue back of the seat together using the remaining “SeatAlignementPins”. Assemble the right and left armrest with the help of the “ArmrestAlignementPins”. Glue one “AdjustmentWheel” on the small cone on each armrest. The armrest parts can then be slipped on the seat underconstruction from the side. At the same time the back of the seat needs to be placed between the armrest parts. Glue the left knob on the left end of the axis from the seat underconstruction. Glue the “RightLeverAxisExtension” in the hole of the “RightLeverOuterPart”. Using the overhang of the axis extension as alignment, glue “RightLeverInnerPart” on the “RightLeverOuterPart”. Now glue the complete right lever on the right end of the axis of the underconstruction of the seat :-) . Ok I hope I got it all covered – have fun.
