Downholder for Eugster OEM coffee machine brewing units

Description

Downholder For Eugster/Frismag Made Coffee Machines. These Include Bosch Benvenuto, Siemens Surpresso, Nivona Caferomatica, Krups Orchestro, Krups Xp, Melitta Caffeo Solo, Lattea, Ci, Bistro, And Lounge Series With A Brewing Unit Similar To The One Pictured (With/Without Grip). This Part Sits Inside The Brewing Unit And Takes Care Of Pressure Regulation. The Original Part Is Made From Abs But Tends To Crack Over Time, Causing The Coffee To Loose Its Taste And Crema (This Is However Also Caused By A Worn Grinder, See Below), But More Notably Half Empty Cups And A Hissing, "Steamy" Noise From Brewing Unit While Brewing. If Your Coffee Started Losing Taste Gradually, It'S Usually A Worn Grinder, If The Loss Happened Rather Quickly And Is Accompanied By The Other Symptoms, It Might Be The Downholder. Take Out Your Brewing Unit And Check The Downholder For Cracks, They Can Be Seen Without Disassembling Anything And Should Be Pretty Obvious. If It'S The Grinder You Can Replace The Grindstones Yourself For About 30€ In Roughly An Hour Of Work And Carefully Re-Adjusting The Grinder Afterwards - There Are Plenty Of Guides Covering That. Note That There Are Two Versions Of How The Part Works. One Uses A Black Rubber Flap That Lies On The Center Block And Attaches To The Part Through The Holes Beside The Block (Pull Through With Tweezers). The Other Uses A Clear Silicon Piece On Top Of The White Part Inside The Brewing Unit, With Nothing Attached To The Downholder. The Downholder Must Withstand Serious Force From Below, So It Should Be Printed With Very High Or Full Infill, Lying On The Fully Flat Side Of The Part With The Big Holes. Also I Recommend At Least 2Mm Of Top And Bottom Skin To Get It Sturdy. External Support Is Required. As The Part Regulates Pressure And Is Responsible For The Taste Of Your Coffee I Recommend Printing It With 100Μm Layer Size Or Less To Keep The Distances As Close To The Original Part As Possible. It Must Sit Really Firm In The Brewing Unit. Regarding Material Imho Pla Should Be Fine Strength-Wise, However The Downholder Might See Some Heat, So Better Check If There Is Any Deformation After A Couple Of Brewings. The Part Itself Does Not Get Into Contact With The Coffee, So Food-Grade Material Should Not Be A Must.
