Description
I designed this spacer to take out the slop from an Olympia Cremina portafilter in a Kafatek Monolith grinder. I added some features to help centre the portafilter and prevent it from vibrating out.
Features:
• reduces slop for Cremina 49mm portafilter
• small ramps hold the portafilter securely in place
• chamfered entrance for easier location
• centres the portafilter under the exit chute
• leaves enough space at the top for different sized dosing funnels
• designed for for an Olympia Cremina 49mm portafilter (~4.5mm flanges), but may fit others
Printer:
Matterhackers Pulse XE
Rafts:
No
Supports:
No
Resolution:
0.1
Infill:
30%
Filament:
Matterhackers NylonXBlack
Notes:
I printed this using Matterhackers NylonX on a Pulse XE.
It should be a pretty easy print. Just put the flat side down, slice with a low layer height (I used 0.1mm), 30% infill (I use gyroid), no need for a brim or supports, and it should be a ~30 minute job.The design relies on an interference fit, so you may need to scale ever so slightly depending on the shrink rate of the material you're printing.
