Rondix 35 - small version adaptation

This a work in progress. NOT TESTED
The idea is to be able to use it as a daylight tank.

**The parts :**
- the top : it is the cover with a hole for the handle and the liquid
- the bottom : the tank itself. There is space for the film cassette and one for the film/liquid
- the axle : the part where you stick your film and then the film got wound around it
- the handle : to turn the axle
- the film lock : **missing** you can probably use a paper clip or print something to keep the film i
