This is full range reed for Alto Saxophone Eb with concerto range D3b-A5 (frequency range 138-880 Hz). Proper articulation and embouchure is required to cover the full range, but it is reachable with ease.
Print with as high quality in Z as your printer and heatbed cover allows. I printed reeds with Z-layer 0.04 mm and initial layer 0.12 mm. This provided 3 layers for 0.2 mm tip thickness and smooth surface. The reed shouldn't be sand-papered, since it already has required vamp profile. It may be post-processed with acetone (since this model is for ABS only by design), but I did not try acetoning myself.

Updates:

• 01/11/2018 - Add new generation base reed with 1.75 hardness. High notes and second register reliability is improved.
• 01/12/2018 - Add reed with 2.0 hardness
• 01/13/2018 - Add reed with 2.5 hardness
• 01/14/2018 - Add reed with 3.0, 3.5 hardness
• 06/24/2018 - Add new version 2 reed with 2.5 hardness for properly balanced vamp for low and high notes. The reed is thinner than before, and sound more natural. 0.4 mm brim is added into problem part when printed with warping ABS.
