### Features - Contacts the basket exterior, since internal funnels leave a void in the coffee grounds - Friction fit to hold basket in place, since magnets barely stick to 304 Stainless Steel - Funnel doesn't have to be held in place, can be flipped upside down without falling off - Follows the basket lip geometry to help avoid grounds getting trapped - Tall enough to not spill grounds during WDT, but short enough for WDT tools - Vertical interior walls, so grounds don't get trapped on the ridges - Curved exterior wall to grip for easy removal ### Printing Features - Flat top for bed adhesion - Thinnest wall is 1.2mm, 3x 0.4mm nozzle widths - No overhangs, all slopes less than 45 degrees, no need for supports ### Baskets Designs for IMS and OEM baskets IMS B652TH27.5M All photos show this basket and design First two photos shows 16.3g of coffee in the basket Links: [imsfiltri](https://imsfiltri.com/prodotto/b652th27-5m/) and [Amazon](https://www.amazon.com/IMS-Competition-Precision-Spaziale-espresso/dp/B07MN5T27X) La Spaziale 0645 ### Print Settings Profile: Normal Wall Line Count: 30 ### Software Used FreeCAD (FCStd files included) Cura ### Notes The design uses an interference fit since 304 Stainless Steel is only slightly responsive to magnetic fields ### Other Designs These were designed for the La Spaziale - [Orphan Espresso](https://www.oehandgrinders.com/oe-stainless-steel-dosing-funnel-53mm) - Stainless Steel, Internal - [SpazGoods on Etsy](https://www.etsy.com/listing/1285660098/53-mm-dosing-funnel-fits-la-spaziale) - External, 66.50mm ID - [maxelman](https://www.printables.com/model/457474-53mm-espresso-dosing-funnel-for-la-spaziale-lucca-) - [Aureum Locus](https://www.aureumlocus.com/en-us/products/barista-tool-coffee-dosing-funnel-use-28530?variant=36813476593821) Most 53mm dosing funnels on Amazon are designed for a Breville and won't fit - [MATOW](https://www.amazon.com/Espresso-MATOW-Stainless-Compatible-Portafilter/dp/B082SWN84Q/) - Jeff L's [Review](https://www.amazon.com/gp/customer-reviews/RCEZVM24Z8O0H/) - [NEOUZA](https://www.amazon.com/NEOUZA-Funnel-Ring-Compatible-Portafilter/dp/B0B1WBV2BH/) - 64mm ID - [IKAPE](https://www.amazon.com/IKAPE-Products-Stainless-Compatible-Portafilter/dp/B09QYTN3R9/) - 63.50mm ID There are quite a few internal designs on Amazon that leave a void much larger than the Orphan Espresso - [TOPINCN](https://www.amazon.com/Dosing-Aluminum-Magnetic-Replacement-Accessory/dp/B08PF5FXXV/) - [Agatige](https://www.amazon.com/Espresso-Dosing-Aluminum-Replacement-Magnetic/dp/B08SBWT7ZV/) - [HERCHR](https://www.amazon.com/Espresso-Aluminum-Magnetic-Replacement-Portafilter/dp/B08RDWZCQL/) ### Food Safety PLA seems to be safe enough for this application based on the following sources, but make that determination for yourself - [All3DP](https://all3dp.com/2/is-pla-food-safe-what-you-really-need-to-know/) - [Wevolver](https://www.wevolver.com/article/food-grade-3d-printing-is-pla-food-safe) - [Sculpeto](https://www.sculpteo.com/en/3d-learning-hub/3d-printing-materials-guide/food-safe-3d-printing-materials/) - [Hatchbox](https://www.hatchbox3d.com/pages/faq)
