Razor Blade Scraper With Cover And 5mm Mounting Hole

thingiverse

The old scraper for my fish tank broke leaving me with a 5mm stick and no scrapper in the end. I took jsc's Razor blade scraper with cover and modified it with a 5mm diameter hole so that an extended handle could be fitted. This first version seems to have an issue where the top of the mount did not print, but it still gripped the pole okay. Be careful when using this tool once you have fitted the standard razor blade. If like me you plan to use this tool in a marine or tropical fish tank, I suggest you thoroughly wash, rinse and give it a short soak outside the tank first. No one wants something toxic leaking from the print material into the water. Consider what you use to print it if you are going to use it around a fish tank. I have printed this in PLA, which is probably not as good an idea as ABS since it might start to biodegrade. I do not plan on having it in the tank for more than five minutes though and I will thoroughly dry it between uses. This is marked as a work in progress because I would like to fix the missing part in the handle. The part works as is for me though. Printer Settings: Printer: Vector 3 Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 20% Notes: You should not need supports. I printed the parts with the flat sides on the bed except for the cover which was printed vertically with the open end up. How I Designed This: I imported the original handle file into Sketchup and thickened the handle, which was a pain because of the rounded surfaces next time I might start with a square. I added a 5mm diameter circle to the end and extended it inside the handle. Only the handle was customized; the lid and cover parts are identical to the original.
