Tealight holder for lithopane

I created a Lithopane of my late Grandad using 'Lithophanes' windows application that can be found here : http://www.imprimindo3d.com.br/software-para-impressao-de-lithophanes/

I then designed a holder in Tinkercad where the tealight sits far enough back that it doesn't heat up the lithopane. the groove in the holder is 2.9mm but this can be easily altered. Have fun printing
