Heatbed grippy adjustment knobs

Just a different style of knobs...and...
I often get confused when I adjust the heatbed about the direction to turn the knob to tight or release the screw...now I easily remember it as the shape is directed towards tightening direction...

You can make this in different sizes with this customizable heatbed knob customizer...

I created these links where you can find all common filaments and spare parts at the best prices. These are just links to selected eBay and Aliexpress items, where I normally buy spare parts and materials for my printer, prices are excellent and products are good. If you buy something from here you will support me a little bit to make these projects.
