This is the TVA TemPad from Loki

The Photos of the print arent100% the files I have published as I have added more detail and minor changes but wont effect print quality,(the renders show the final product)

This uses two 6x3mm magnets to lock part 2 into part 1.

For the hinge I used a paperclip to hold it together

All the measurements and designs etc… are based of guesses from photos
