Shaffer Linear Processor v3

UPDATE: I've written up some additional construction tips at https://clydeshaffer.com/slp/posts/01_how2build.php

I'll admit: I've been slacking off! It's been way too long since I released a full set of files to match the improvements I've made to the SLP both in build difficulty and usability.

One big change that I'm particularly proud of is the fully 3D-printable film puller. With this, you won't have to salvage a sprocket unit from a projector and (importantly) won't have to painstakingly measure it to position the mounting holes.

Additionally, with the introduction of a spacer piece to place between tanks the need for a bulky external frame is eliminated. If flat-ended PVC caps are used for the tanks, they will stand freely. I recommend using epoxy to attach the spacers to the tanks, and arranging them so that the top spacer is on one side with the bottom spacer on the opposite side so you can put as many tanks in a row as you like.

The same files will also be available
