Started playing Magic The Gathering, but I often forget e.g. to draw a card. Shortened the original to 7 checkmarks and created my personal MTG Phase reminder.
@Callidus2000 Very cool!
Little improve idea: Notches to slightly fix positions of the switches.
So you can take it with you and dont be afraid that it changes unwanted by itself.
@Phil_243945 other Makes would have to confirm this, but adding Super Lube keeps the sliders in place quite well in my experience. But I could add an indent or notch perhaps. Thanks for the suggestion (edited)
I have taken bearings apart before and this looks like it will help. Put in in the storage case with some bearings for a future project.
@clw_35062 Appreciate the comment+photo!
Simple print. Works Great.
