This model ist based on the linked Model and only contains the Front-Panel. You have to use the original Backplate- & Slider-Files

With the exception of the first two "Task-Slides", I added a tight-fit mould to clip in a blank ID/Credit/RFID/NFC-Card to add handwritten/custom/quickly changing Tasks with any dry-erase marker.

You can buy the empty/white cards here (affiliate Link!) https://amzn.to/476NTrb or use any other credit-card-shaped ---thing.

I use Non-Permanent Stabilo OHPen universal.
