Hej Ebar

Nu har folk her på siden været gode til at dele div. arduino koder og projekter, så tænkte at det måske var på tide med noget ligende for 3Dprint. Der er jo efterhånden en del der printer, så mon ikke at vi kan nyde godt af hinandens ideer og tegninger

Har selv lidt forskellige projekter i støbeskeens, bla. et "steam-stop" til drypbakken der skal forhindre at vand og mælkerester bliver blæst ud over alt poleret metal, shot-spejl og bordet :P Steam armen på Elektra A3 svæver et godt stykke over bakken og derfor ender vandet over alt, hvis man ikke bruger en klud ved udluftning. Designet skal ændres lidt, men ideen ser ud til at virke ok og så skal det selvfølgelig laves i metal

First prototype

En anden ting jeg har leget lidt med "OCD tool". Har lavet en plastik version, den virker fint nok, men synes ikke at den gør nogen forskel i koppen, men måske den kan gøre en forskel for dem der har problemer med channeling..?

Hvis folk ikke keder OCD:

Flere prints, ideer og spam på vej

To vinkler til denne tråd.

1 Fed ide, "sharing is caring"

2 Damm you - nu bliver vi jo lokket til at købe sådan en printer...

LOL

Men mest nummer 1

Har selvfølgelig opgraderet, så har faktisk en 3D Printer du kan købe, skal ikke komme an på det da

Dyrlægen - Skide godt initiativ, især når 3d printere bliver mere og mere tilgængelige, så hvorfor ikke samle alle de gode ideer vi får. Jeg har en masse forskellige modeller jeg vil ligge op når jeg er kommet hjem fra søen. Låg til likørtragt, tamper stand, de ret så bruge tragte osv

**Kaffe T** · 18. February 2016, 09:07

Jer med erfaring med 3D print - hvor stærk er materialet, der printes i ?

Jeg mistede mit yndlingshårspænde på KaffeShow i Århus. Og lige præcis den type kan ikke opdrives mere. Suk.

Det er et Ø-spænde: altså en oval ring, hvor man bruger en løs pind til fæstne håret med.

Men den ovale ring skal være ret stærk (jeg har langt hår og det er tungt, når man vikler det sammen og skal ha holdt det fast på baghovedet). Nogen chance for at 3D print er stærkt nok til det ?

Det ville måske godt kunne lade sig gøre tror jeg, evt i noget PET eller Nylon plast, måske endda ABS. Jeg vil i hvertfald gerne give det et forsøg hvis det er. Dog har jeg kun ABS lige pt, men da et forsøg hver

Lidt om de forskellige plast typer her. PLA og ABS er klart mest udbredt - https://www.matterhackers.com/3d-pri...lament-compare

Øv, jeg vidste det...

Hvorfor har du opgraderet og hvad skal den gamle koste..?

**Citrushund** · 18. February 2016, 10:54

Ville godt have en lukket printer og så blev jeg nød til at prøve kræfter med dual printing. Dog stadig til gode at prøve det

Den nye er en Wanhao Duplicator 4S

Den gamle er en Mendel90 udviklet af en britte Nophead, pris mæssigt ligger vi omkring 3000kr inkl en masse forskelligt plast. Nypris var ca 6500kr

Er der én af jer 3D rødder der har printet en portafilter stand til vægten? Kunne godt bruge den til min kommende Brewista Smart Scale istedet for at skulle investere i den større Acaia Pearl Scale.

Tampstand for Rocket Espresso Portafilter (E61 brewhead) by rtrski

http://www.thingiverse.com/thing:35538

NOTE (Update 18 Mar 2022): Weird I coincidentally last updated exactly a year ago. Anyway, based on our new 2021 model year Rocket Mozzafiato, both the 'step' at the handle diameter and the 'slope' of the far side basket support of this tamp stands is no longer compatible with the new Rocket machines. Apologies for anyone who has printed it and found the design wanting; I don't know how far back that design change might go. I have a new design I'm using myself that's laser-cuttable that will regrettably not be uploaded here. NOTE (Update 18 Mar 2021): Pictures of made item (Red ABS) are old version, please download at least v6 file for better single/dual spout compatibility!! "Tampstand Penetrated" file is v6 plus holes for reinforcement - see below.) Espresso makes me happy. Tamping a single spout portafilter without a tamp stand makes me sad. Paying a ludicrous $80 or more for a stainless steel and marble-inlaid, buffed-with-virginal-baby-diaper-soft-cotton tampstand with some bozo logo on it makes me angry. Me without espresso with a rich thick crema from the perfect grind and tamp, angry, makes the world a scary place. I need to not be angry. Hence, the swooshy blended just-strong-enough it flexes a little to let me know when I'm tamping just right, ABS tampstand. In red, because Rockets have red glare. :) 5/11/2014: Updated with a v6 file with less faceting. My original finally got overstressed and cracked, so rather than just reprint I did some redesign. The new version fits both the single and dual spout portafilters and provides a bit more strength. Since I needed an 'undercut' for the dual spout, the new file has integral support parts that are part of the print. I prefer to design these in rather than let my slicer provide them since I can better control contact points and removability without excessively marring the desired finished part. 03/18/2021: Well, after many years of use again, I broke my print mid tamp. Makes for a bitter cup. ;-) So finally did something I've been meaning to for some time, even though I no longer have the original Creo file made my stl from, so only had the mesh to work with. I was able to import the v6 file with integrated supports and Meshmix it to add a couple of 3.2mm holes thru the main body height. These might help with reinforcement on their own, but they're about right for 8d 2.5inch bright finish nails: coat them good with E6000 or drip some good liquid superglue into the holes (tape the bottoms!) then tap the tight heads down gently with a hammer, clean up any surface smears, and hopefully the nails will help prevent breakage in the future. (You could also use 0.125in dia rod stock if you can find it, or just trim lengths of 2.85mm filament and probably thread them in, not sure about glue technique in that case (insert all the way thru dry with plenty of excess, apply glue to protruding section and pull thru from other side, then trim both faces after?). Anyway, happy to see one of my early naive attempts at designing something useful has actually had several makes and many likes and collects over the years. Happy caffeination!

Jeg har ikke selv printet sådan en bandit, men hvis du tager forbi RUC fablab, så er det næsten gratis at bruge deres 3D printere og de har mange! Bare vær opmærksom på at PLA ikke dur til temperatur over 45 grader, så en ABS printer vil være at foretrække

Det er en kæmpe klods at printe, hvis den skal have en pæn finish (6-10 timer!)

**RasmusDJ** · 18. February 2016, 16:16

Den må jeg lige få testet af.

De har flere 3D printere på RUC Fablab, jeg har dog oplevet at det ikke altid virker, eller at der er udfordringer med dem. Jeg tænker at jeg skal prøve at printe noget i morgen derhenne, hvis det eller lykkedes denne gang.

Jeg skal printe en til SQLCPH, kan også printe en til dig hvis du ønsker

Det ville være fantastisk!! Det må du meget gerne

Lækker dims! Men apropos Brewista, så kan man også fint bruge coveret:
