Pneumatic Office Gaming Chair Drop Fix Brace Print in Place

thingiverse

Since the OP mentioned using a zip tie or something to support the top, I decided to remix it fast in tinkercad, I'd rather have pins if possible. Included OP pin stl along with what I call V2. From the original by cwills75: My office chair's pneumatic lift wouldn't stay up anymore, so I over-engineered a print-in-place support brace for it. The tolerances for the hinges are 0.3mm, so watch your slicer settings (especially if scaling). I was going to print at 0.2mm but it looked the like top hinge would fuse, so I dropped it to 0.15 and it was fine. After removing the supports it rotated very cleanly. I would recommend adding a zip-tie around the top of it to help it's rigidity. Scaling the width shouldn't be much of a problem with anything as long as you go bigger (smaller will shrink the hinge pin gap tolerance also). Without scaling the height, it could be a few inches shorter by either/or moving it down through the z-axis plane or telling your slicer to stop printing a few lines short. If you go too much, you'll start cutting into the hinge. I've added a picture in Simplify3D with automatic supports enabled. That's what I used and it worked well. Print Settings Printer: Qidi X-Plus Rafts: No Supports: Yes Resolution: 0.15 Infill: 20% Filament_brand: 3D Solutech Filament_color: Real Black Filament_material: PLA Notes: Read main description on scaling advice, but biggest thing is check your slicer's layer-by-layer preview where the hinges are to see that they won't fuse with too high of a layer height. 0.15 worked for me. 0.20 looked like it wouldn't for part of it. Post-Printing 1. Remove supports. 2. Rotate hinge. 3. Install on chair. 4. Insert pin. 5. Great success ;) How I Designed This Fusion 360
