The True Tamper

thingiverse

No matter how meticulously I tried, I occasionally ended up with uneven tamps using a traditional tamper. There are plenty of new wave tampers on the market right now that combat this problem but they create another one, a hole in my wallet... I set out to make a simple tamper that insured even, or "true" tamps each and every time. In addition I wanted stepless depth adjustment that was able to be changed on the fly without any additional tools. This design is what I ended up with. It's designed around an E61 58mm portafilter basket. The Espresso Parts HQ 14g Double to be exact. The four I own measure ~58.95mm ID. This tamper has an OD of 58.90mm. Print Settings Printer: Kossel Mini Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Notes: Bottom Layers: 3 Top Layers: 3 Shells: 3 Instructions It fits perfectly snug for me but that doesn't mean it will for you. There are too many variables, from printer setup, to different basket manufactures. For best results, measure the inner diameter and scale these parts accordingly. I've optimized the threads the best I can for printing but I recommend printing the lock ring and body 1.0% larger than the base.
