15mm OD x 4mm ID x 1mm Thick Washer

thingiverse

After achieving phenomenal success with the 15mm Furniture Foot, I decided to create a washer by extruding the base layer into a washer shape directly. No elaborate intermediate steps this time; I went straight for the solution and made a washer from scratch. I know what you're thinking! Anyway, the truth is that I loved how the Furniture Foot performed in real-world prints from TPU, so I decided to mass-produce some TPU washers. The earlier washer design for Robo 3D tensioner screws was great, but I wanted something with a #6 (4mm) center hole and a larger outer diameter of 15mm. So, the dimensions are as follows: 15mm OD x 4mm ID x 1mm Thick. This makes them incredibly versatile for various applications. In the near future, I plan to create a comprehensive washer pack covering all basic needs. Tiny washers, big washers - you name it! From TO-220 heatsink washers to garden hose gasket type washers, everything will be taken care of. Then, neither you nor I will ever need to visit Lowes for a washer again, at least until the printer breaks on Tuesday. Printer Settings: Printer Brand: Robo 3D Printer Model: R1 ABS + PLA Model Rafts: No Supports: No Resolution: Whatever works best Infill: Solid, no less than 100%. I mean it! Notes: These washers print beautifully in TPU. I'm using the black Hatchbox 1.75mm filament. Here are my basic settings: Extruder Temperature: 240C (slightly overkill, but it flows great) Hotbed Temperature: 110C (definitely overkill, but I'm in a hurry) My hotbed is an aluminum plate with a thickness of 1/8 inch. I usually use Pledge Floor Finish as a prep, but today I'm using Aquanet Super Hold Unscented due to last night's mayhem with PETG. It sticks amazingly well, maybe even a bit too much. Extruder Flow Rate: 0.95 Retraction: 1.5mm at 60mm/sec Print Speed: 60mm/sec (crazy, right? But it works for now) Z Offset: 0.7mm (seems to work well) I also kept my PETG settings of 200% width, 90% height, and 20% speed on the first layer, as I'm short on time and don't want to mess around with the printer after all the issues with PETG. If everything goes smoothly in a print, I won't change anything until Christmas. One major advantage is that I'm using an E3D V6 Hotend. This thing is more forgiving than my old Hexagon hotend, works better with exotic materials like TPU. Still have some issues here and there, but it's easier to understand what causes them now. Yes, installing this hotend on a Robo 3D was a wild ride! I tried to forget all the headaches of that day. Despite my best efforts, the hotend came loose on day four. I never cursed so much in my life, not even during my first relationship! But it's still the best hotend I've had. It really likes TPU.
