Fish tank scrapper - credit card format

I designed this scratcher to fit the old credit card. Which in my opinion best removes algae from the aquarium glass. Please remember that the project is still in testing, so you do everything on your own responsibility.

scrapper-holder is designed that way you can print many and put togehter to have longer holder.

scrapper-base-v2.stl - the gap on the credit card is wider

NOTICE: Please use an old valid credit card
