Franke Soap Pump Shell

The original Franke soap pump has a design issue making it too fragile to support repetitive spring compressions. After 3 successful repairs with glue, I have not been able to repair it anymore. As the spare part by Franke costs the price of an Anycubic 3D printer. I decided to go the 3D printer route and I am really glad I took this option since I can use the printer for many other cool projects as well...

Here is how you should print and assemble the part.

1. Make sure you did not apply some axis calibration by measuring a printed part. This is a complete non-sense. Your stepper motors and pulleys gives an exact value to compute from tech sheets. (Usually in the metric world it is round and exact numbers like 400 and never ever 387.8. Eg for AnyCubic Mega S: M92 X80.00 Y80.00 Z400.00 E400.00)
2. Scaling of 3D printed part should be based on thermal coefficient of your printed material and delta temperature (eg: printing PLA, around X and Y axis requires +1.224% model upscale f
