Retainer ring removal tool for a Saab fuel pump

Here's a tool I made to take out the retainer ring for a Saab fuel pump. Took forever to print (8-9 hours, 0.3mm layers, 25% hex infill, PLA on a Printrbot Simple Metal with a brim) and took up most the build volume, but printed perfectly. It's for a 2000 Saab 9-5 (the lower end one with a mild turbo, not the performance version), but I think it fits most all the Saabs in that timeframe and perhaps some other cars as well. I attached the OpenScad file as well.

Stick a long screwdriver or rod through the holes to give you leverage to remove the retainer ring.

Again, it's over-built. Doesn't need to be so thick or with as much infill. It's also about 1cm taller than it absolutely needs to be.
