Rondix 35 - small version adaptation

thingiverse

This is a work in progress, not tested. The plan is to use it as a daylight tank. Here are the components: The top: this houses a hole for the handle and the liquid container. The bottom: this is the main tank itself, featuring space for the film cassette and one for the film/liquid mixture. The axle: this is where you insert your film, which then gets wound around it. The handle: used to turn the axle. The film lock: currently missing; a paper clip or printed part could be used instead. The locking tab: also missing, necessary for securing the top to the bottom. A M3 screw can temporarily hold it in place. How to operate: Insert one end of the film into the axle and secure it with something (a paper clip could work). Place the top on the bottom. Secure the top with an M3 screw and a small tab. Attach the handle. Add liquid to the tank. Turn the handle to unwind the film from the cassette to the tank. Develop the film like in a standard development process. The main drawbacks I've identified: Pouring liquid into it is extremely difficult due to the narrow pouring hole. It may leak. I'm unsure if it's light-tight (?). Untested. Any suggestions are welcome. How It Was Designed My goal was to replicate the Rondix 35 design, which initially seemed too large. I wanted to position the film vertically instead of horizontally since I saw no reason why this wouldn't work. By doing so, I avoided dealing with a potential leak near the handle, my main concern in previous designs.
