This is yet another 5th Element inspired Covid vaccination card holder. It's also a remix from level2three who has removed the design from here but has it available on PrusaPrinters.org (https://www.prusaprinters.org/prints/67610-vaccination-multipass-holder)

I made 3 changes to the original:

1 - I made the indent to hold the filament bar deeper to secure the filament better. It fits 1.75mm filament nicely

2 - I took out the dome and left a flat surface

3 - I added an integral brim to the stopper since it won't print without one and not all slicers let you add a brim to a single piece

The dome area fits 1 inch/25mm clear glass blobs/circles used in making jewelry. That gives clarity (yay!) and weight(not so yay). To make it look yellow I glued down a layer of tinfoil then mixed yellow paint with white glue for the blob. Overall it works nicely. Be careful of using too much glue since there is space around the blob and it will ooze up.

Be sparing with the superglue when assembling because any that oozes out into the card slot will stay active until you put the card in, with obvious results.

The brim on the stopper isn't really a brim. Most of it will peel off nicely but may leave a ridge that can be shaved off with a craft knife.

The white and red are paint.

Don't cut out the pass or the plastic (if using) to try to help the stopper fit into the hole better. It doesn't stay closed as well that way. The card/plastic are what friction fit it into place.
