Windshield Washer Tank Cap

thingiverse

As you can see in the 2nd image, the windshield washer tank cap for my Winnebago Itasca Sunrise motor home started to fall apart (a GM Workhorse Chassis). This OEM cap has an outside retaining lip diameter of 47mm. **PLA Version** - Washer Tank Cap No-Collar.stl The cap without the retaining collar is meant to print in PLA. It has the same 47mm inside diameter as the factory version but it fits best when printed at 98% in the X & Y axis: Leave Z at 100%. **TPU Version** - Washer Tank Cap W-Collar.stl This is my first print with TPU. I was extremely pleased at how well it printed and flexed. I set the temp to 210 C, the flow to 103% and the print speed to 30mm/s. Layer thickness was 0.2mm and the bed temp was 70. Retraction distance 6.5mm and retraction speed 25mm/s. [3D BEST-Q Flexible TPU ](https://www.amazon.com/3D-BEST-Q-Flexible-Filament-Dimensional/dp/B078HYXN2N/ref=sr_1_3?s=industrial&ie=UTF8&qid=1532905014&sr=1-3&keywords=3D%2BBEST-Q%2BFlexible%2BTPU%2BBlack%2B1.75mm&th=1) **Final Note:** You can use my 47mm cap measurement to calculate a scaling percentage for other cap sizes. Divide your cap's measurement by 47 and multiply by 100 = Your scaling value percentage. **Example:** 55 / 47 X 100 = 134% on the X & Y axis only. After doing a test print tweak the scaling factor further to adjust for fit. **-VegasGuy** *Check out my [designs page](http://www.thingiverse.com/VegasGuy/designs/) to see other useful things I have made for my RV.*
