Volumetric WPC Scoops

thingiverse

These are a series of scoops designed specifically for WPC from Bulk Nutrients. These scoops were created to simplify the process of working a shake into your macros, eliminating the need for complex math calculations. If I require 35 grams of protein, that's achieved with one scoop of the 15g and another scoop of the 20g. Bulk Nutrients' WPC is known for its high purity level, boasting around 77-80% protein content. A nominal protein concentration of 77% was used in this design, which is at the lower end of the expected range, ensuring that users can be confident they will always receive at least as much protein as desired. Some suitable but untested protein powders include Optimum Gold, True WPC80, and Venom WPC. Note: I spent 40 minutes searching for other well-known WPC powders with similar protein content, but only Optimum fit the criteria. If you're not already supporting local protein manufacturers, now's a great time to start. The design utilizes my experimentally derived density of WPC (~0.38 g/mL) along with a previously explained protein concentration of 77% to determine the volume of the scoops. They are designed to be printed "right way up" and utilize a base overhang angle of 40 degrees. If your printer + material combo can't handle this level of overhang, results may not be optimal. The cups feature two unique elements: a pointed "beak" and a slanted top. The beak enables the scoops to more effectively scrape protein from the walls, and the awkward pockets often left at the end of a bag. The slanted roof makes it easier to flatten and level the cup without your thumb getting in the way. This is particularly relevant for these scoops as the handles aren't flat and can be somewhat inconvenient. There are three different scoops available: * 15g of actual protein (19g of powder weight) * 20g of actual protein (26g of powder weight) * 30g of actual protein (39g of powder weight) I have printed all of them and checked their accuracy on a scale, which can be seen in the pictures. These cups were printed at 0.1 mm layer heights to look good, but this can be printed 0.3 mm without impacting accuracy. The text on the handle may not appear as crisp, though. Note: Unlike creatine, WPC is easily compressed. If you pack it too tightly, you'll have excess protein. Conversely, if you don't press hard enough to eliminate air pockets, you won't have enough. I recommend checking your technique with some kitchen scales to ensure accurate measurements. Remember to check the measured weight against the "powder weight," not the "actual protein" weights.
