Paint Stir Blade - Stir Propeller - 2 Versions - Metric and Inch
Description
PDFThe last time I had a painting project, I wished I had one of these - so I made this for my next painting project.
This print requires a length of metal rod about 10" (250mm) in length (the exact length is not critical). I created files for different rod diameters as follows :
- 02A = ¼"
- 02B = 5/16"
- 02M5 = 5mm
- 02M8 = 8mm
In addition to the above sizes, I have included a HubTest print for each size - you can print this out and test the fit on your chosen rod diameter; if necessary you can scale the print up or down to get a tight fit.
Assembly and Use
Note that the blade has a top and a bottom (blade curve on top, straighter part on bottom). Place the blade top side up on a flat surface and tap the metal rod into the hub with a hammer - it should be a tight fit.
The blade diameter is 50mm, so your paint container will need an opening bigger than that. Insert the rod into your drill chuck as shown in the photo. To stir paint, insert the blade just under the paint surface at first, and stir under the entire surface; then move the blade down a bit and repeat, and so on to the bottom of your container. It is not advisable to move the stirrer up and down in the paint as the spinning rod will throw off paint once it has been submerged.
The blade is designed to spin clockwise (looking down) so that it pushes paint toward the bottom of the container. Spinning in reverse is not advised!
After use, I cleaned the stirrer by spinning it in an empty garbage can with a plastic bag liner, followed by rinsing with water (for latex paint).
Print Instructions
I printed the blade in PETG on a textured bed; use the 3mf file provided; otherwise :
- print top side up on the build plate (see photo)
- 0.3mm layer height
- 2 perimeters
- no brim required
- no supports required
