I am working on Version 2, with the shorter neck first. Instead of using a threaded rod inside the neck, I'm now using a vertical aluminum strip (2 x 15mm) glued into the neck, which provides much better stiffness and prevents bending under string tension.
Now it's finally here

Update 2023-05-09
Added alternative Bridges as .3MF and .STL due to the fact that the string-force bends slightly over time so you may have to change to a lower bridge.Update 2023-05-09 evening
Added a tuning-section, see below
Update 2023-05-10
Added alternative Nuts as .STL, the 2.5mm is the default
Updated Nut
Add 2023-05-13
Added StringWinder section under Print- and Model- files
One with crank and an adaptor for a bits screwdriver
Added Sheet Music under Other Files
Update 2023-05-14
Crank socket was a bit too tight
Update 2023-06-05
Images (at the bottom of this page) of the short neck(files under STL) banjo with ukulele strings attached. Works well.
If you have any problems don't hesitate to contact me, I don't bite!

Left the Banjo in the sun. Not good! String tension!

| Preface | |
This was a challenge. Should the banjo be playable? Will it be too wobbly? But YES, it's playable. All the parts are printed with Prusament PLA. The body itself should actually have a heavy iron ring in it, but we'll leave that out for now. Tuning is not entirely easy to achieve, the bridge must be at the right distance and sit at a slight angle so that the notes of the strings "come together". The strings are for standard Tenor Banjo and must be CGDA tuned. There is also Irish tuning GDAE but requires different strings. Under other files I've put a zip-file with sounds that I have recorded, not the best quality but anyway. Regarding tuning and placing the bridge I will try to add that later on. |
| Instructions | |
| 1 | Print the parts |
| Settings as in the .3MF files | |
| When printing Banjo_DotsNutsFitPlugs choose a suitable color (for the fretboard dots) | |
Remove the brim from the neck/fretboard If the neck/fretboard warps they become useless!!! Happend to me several times! I have noticed that if printing diagonal they don't warp?!! Anyone had the same experience? | |
 | |
| 2 | Glue upper and lower necks together |
| Use the small fitplugs and quick clamps to hold them together, be precise! | |
  | |
| 3 | Glue the dots to the fretboard |
| Put a drop of glue to the dots and set them in place. The dot is smaller than the hole so it will fit without any problem. | |
 | |
| 4 | No more gluing now! :-) |
| Except for the plectrum/pick holder later on | |
| 5 | Cut the one meter threaded rod into 4 pieces |
| Main rod 380 mm | |
| Heel rod 55 mm | |
| Two body rods 175 mm each | |
| Leftover rod ~210mm (We might use 195mm of it it for a strap-knob later on) | |
 | |
| 6 | Attach the tuning set to the PegHead |
| Push the tuner screws through the holes on the peghead and use the small screws to secure them | |
| Note that the top inserts that comes with the set is not to be used | |
  | |
| 7 | Take the PegHead and screw on to the 330 mm threaded rod. |
| Use a plier to hold the rod while screwing. | |
| You will notice when it is fully screwed in. | |
 | |
| 8 | Attach the 55mm threaded rod to the heel of the second neck/fretboard |
| Use a plier to hold the rod while screwing. | |
 | |
| 9 | Attach the plugs to the neck/fretboard |
| The two small plugs to the first neck and the four other plugs to the second neck | |
 | |
| 10 | Attach the nut and the fretboard |
| The sloping side of the nut should be towards the head | |
| The plugs can be a little difficult to get in, but it should work | |
  | |
| 11 | Attach the body to the threaded rods of the neck/fretboard |
| Take the two M8 nuts (13 mm head) and screw on tightly to the rods | |
  | |
| 12 | Attach the two 175 mm threaded rods to the body |
| When you insert the rods you shall screw on two nuts on each rod | |
| Tighten slightly with your hands (Do not use a tool, something may break) | |
   | |
| 13 | Attach the drumhead to the body |
| Can be a little tricky, you may have to use a quick clamp to fully get it into place | |
 | |
| 14 | Tighten the nuts at the end of the 175 mm threaded rods |
| See 12 above | |
| Again, use handpower here, if you use tools something may break | |
| What happens here is that the drumhead will be stretched a bit giving a higher tone. | |
| 15 | Optional, Attach the resonater |
| Use the two bolts and the M8 tool | |
 | |
| 16 | Optional, Glue on the plectrum/pick holder to the body |
 And maybe a fancy g-clef to the peghead  | |
| 17 | Attach the strings |
| Normally the strings are loop-end but ball-end string could be used as well | |
| There are five pins at the end of the body but for loop-end string you only use four of them | |
| Attach the strings one after one, put them on the bridge | |
  | |
| Tuning | |
 CGDA e.g. 4:th string (thickest) pressed at fret 7 shall give the samt tone as 3:rd string and so on |
Will never be exact!

The shortneck is under the STL files     |
