Recorder V2 (instrument) by cymon Oct 3, 2011

Description

Version 2.1b has been confirm as functional! Thanks nycdesigner and tbuser for sticking with me!

This is a complete rebuild of the recorder instruments with more scientific measurements and a more sound theory as well as an entirely unique and slick design.

The recorder is one of the oldest woodwind instruments. In the hands of an experienced player it creates a sound synonymous with Renaissance music. Often used in elementary music classes because of it's ease of operation. With 3D printing everyone can have one of their own to make beautiful music on... or wailing screeches if they never got past "hot crossed buns".

Ever since I've seen the whistle ( thingiverse.com/thing:1046 ) and it's variations ( thingiverse.com/thing:1046/variations ) I've wondered about the feasibility of extending it to a flute. However when I finally did decide to tackle it I ended up designing the whole thing from scratch (which is why this isn't a derivative of the whistle).

Version History:
Ver2.0 - recorderv2mouthpiece.stl + recorderv2body.stl + recorderv2foot.stl: The mouthpiece in this version is the tallest piece at about 119.3mm which is cutting it too close for a TOM.

Ver2.1a - recorderv2.1amouthpiece.stl + recorderv2.1body.stl + recorderv2foot.stl: Per input from nycdesigner and tbuser the ring around the base of the parts has been widened to increase stability during print, the mouthpiece has been altered with a shorter windway and 1mm taller window. This brings the mouthpiece to being short enough for a TOM and does not effect tuning tho it may require slightly more air to work.

Ver2.1b - recorderv2.1amouthpiece.stl + recorderv2.1body.stl + recorderv2foot.stl: Same as 2.1a except the windway now slopes towards the lip. tbuser found that worked best for his 6 hole flute ( thingiverse.com/thing:11945 ) so I've included it for experimentation.

Thank you cymon! Very nice design, just needed to fix geometry (wholes?) in netfabb. Looks great and hope to electro-plate this with Brass in future.

Ya, I really don't know if just the lower or all of them. If you want to just start with the lower e-mail me the .stl and I'll see if it makes any difference.

I've got 15 rolls of ABS on the way so I'm game for some iterative design ;)

I'd like to see how it sounds when made from PLA instead of abs, too.

The ridge has been added to Recorder v2.2.

Just to be clear you're talking about undercutting just the lower note holes? How many? The wall around the last 2 fingers are already pretty thin due to the finger grooves but I could always try.

Instructions

Print the 3 parts. Put them together. Warm up the mouthpiece with your hand before playing for best sound. Blow gently.

Note that if you start with all holes covered and remove them one-by-one that the high notes are going to sound flat. That is normal. To get the proper tones for all the notes use the key chart on en.wikipedia.org/wiki/Recorder#Recorder_fingering .

It plays OK! I printed 2.1B

Some suggestions for improvements:

Longer joints between sections. The top piece fits tight enough without any glue, but needs more leeway for tuning.

Tighter foot joint: The mouthpiece/upper joint was perfect. The foot/upper joint was quite loose?

Also, something felt off with the last 2 n
otes. It seems choked, but just playable.Maybe just my inexperience with the recorder. (I'm a pretty good clarinet player, though)

Can you post a video playing the whole octave please?

cymon on Oct 7, 2011 said:

Your little suggestion has warrented huge changes. In lengthening the mouthpiece upper body joint means I need to move the joint between the body and the foot which makes the body too big so I need to break it in 2, which is actually better because it means you can adjust the pinky angle yourself, but I've been resisting.

The next version will probably be it's new derivative. When this is done EVERYONE will have a printed recorder.

Anybody know if this one works yet?

There is a photo of my ver 2.1d

Oh, by the way, snagged as the thumbnail because it's so pretty.

cymon on Oct 6, 2011 said:

I assume you mean 2.1b with the sloped mouthpiece. Does it play? How does it sound?

Can you send one to Richard Stallman? I'll bet he'd get a kick out of receiving his favorite instrument constructed via open source technology.

It looks as if it's a gnat's eyelash too long for my TOM using the heated platform.

cymon on Oct 5, 2011 said:

Well you're in luck. Version mouthpieces 2.1a and 2.1b are both TOM friendly now. Let me know if you print it and if it works for you.
