Eureka Mignon Sliding Portafilter Holder

Simple sliding portafilter holder for the Eureka Mignon Crono. Should work on newer Mignons. I only tested this on the Crono.

This is tall enough to minimize grind spray. With magnetic dosing funnel, you should be able to slide this forward to tap the grind button.

3/16/25 Update: Minor update on the Gaggia slider to increase polys and general clean up on the model. It's much smoother and round rather than blocky. Added an optional version with spine to increase rigidity.

12/1/23 Update: Updated to reduce the height of the key. The slider should now sit flush against the base plate. The old version is included in Archive folder and offers float and reduce friction.

Designed with the following in mind:

• Standard 58mm Portafilter, straight back handle (I used a Decent). Clears my spouted EspressoParts 58mm portafilter.
  • 12/1/23 Update: Updated with a shorter key to fix the wobble. There is now about a 0.5mm clearance between the slot and the key. I have not tested this version.
• Gaggia 58mm Portafilter is also included, but I have not tested this version.
  • 12/1/23 Update: V2 - Updated with a shorter key to fix the wobble. There is now about a 0.5mm clearance between the slot and the key. I have not tested this version.
  • 3/15/25 Update: V3 - Clean up minor artifacts, increase polys for rounder surfaces. Added Spine version
• Matched to Oelsi's tilted base: https://www.thingiverse.com/thing:4937910
• Short magnetic dosing funnel to actuate the grind button by pushing the portafilter forward. I use this one: https://www.amazon.com/dp/B08SBLCQST?ref_=cm_sw_r_cp_ud_dp_224NX76J81B504NRKRZZ
• There are two trays. Short and Long. Longer one should support the portafilter holder better (it's about 40ish-mm longer). The short is for those with space constraints and works best when the portafilter is weighing down the holder.

Simple remix of two great designs:
