This folding scalpel handle is stronger and stiffer and can accommodate all #4 scalpel handle blades (up to 60mm in total length).  I have tested it with #18, #20, #21, #22, #23, #24 and SwitchBack blades.  

The pivot utilizes an offset radii design allowing it to print easily and still rotate tight in the open and closed positions.  Check it out!

100% printed - no hardware, fasteners, or adhesives required.  No support required

Print Settings:

I have tested this design on multiple printers using PETG, ABS+ and PLA.  Print settings can vary significantly between users so please note my settings and let me know if you are having difficulty.  I am committed to helping everyone get great print results to the extent I can so please contact me if you are having issues.

**Revisions and Updates**
I occasionally update and revise my designs. When I do, I’ll document the changes here. Check back periodically for the latest revision notes or if you’re experiencing any issues with a model.  

2024-07-26 Update: This is now version 2.1 of this knife which now has improved geometry to help keep the blade closed and or opened as well as a detent on the closed side to minimize the chances of it partially opening in your pocket.  





Folding Scalpel Pocket Knife v2.1

Folding Scalpel 2v11d__Standard.stl

If the kids are playing in the pool or running around in the backyard, this pool noodle sword will elevate their sword game! These work with a small pool noodle with a 1” (25mm) hole. Designed to be printed helm up and handle up, they easily thread together so you can get your battle time going! The pool noodle fits snugly onto the insert so it doesn’t come off during your duels! 

**Printing Directions:
Outer layers > 3
Infill > 50%**

These need strength. The connection between the helm and the insert is a breaking point if you go light on layers and infill. Also, try to keep the blade (noodle) to 12 – 16”. Longer blades add more stress when the kids actually hit something. 

Make sure to check out the other swords!

Knife Prop

Mini Matchete

blade.stl

This is a scalpel holder desktop station with integrated automatic blade removal and blade capture.  It has blade storage and a blade insertion tool as well.  It is a fun contraption for displaying your 3D printing skills.   And, it makes the perfect desktop device for anyone who likes to use and keep a scalpel handy.    

100% printed, snap-together - no hardware, fasteners, or adhesives required.

Do not add support, it has built-in support where needed.

UPDATE: 2024-06-26 I just added a #3 handle as well. The original #4 handle works better, but I did get the #3 handle to work with some blades I have.  So if you have blades for the #3 handle please feel free to give this a try.  But I still recommend and prefer the #4 handle and blades.

Print Settings:
 
Material = PETG, PLA, or ABS 
Nozzle = 0.4mm
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%
Ironing = ON (recommended but not critical)

Scalpel Station Widget - with Auto Blade Removal and Capture

Straight Scalpel 1v00a__Base_ (1).stl

I have a significantly improved version of this knife which accepts a wide range of blades, version 2.0 posted here...
https://than.gs/m/1092890

-----------------------------------------------
This is a 100% printed and print-in-place folding scalpel.   No hardware or fasteners required.  The scalpel is small, super light (about 8g) and very convenient. I have added a pressure point on the top of the blade which conventional scalpels do not typically have. This helps to give you a safe place to put your index finger and also allows you to comfortably apply pressure when cutting. It is important to note this knife, like all scalpels, is designed to be held like a pencil.

There are 3 different STLs with varying tolerances so you can hopefully find the one that prints best for your setup.  The knife should be super tight after printing.  And, freeing the print-in-place parts is a little more onerous than usual so please take care to work the parts free carefully.  Once the parts are free the knife should work for a long time.  

Inserting and removing the #18 scalpel blade is normal.  The first time inserting a blade it will be a little tight but after that, it will be very smooth.

I have just added a modified version of this file which I think will accommodate a #24 blade as well as a #18 blade.  But I need someone to test it and let me know.

Pool Noodle Sword - Arabian Knight

**Added R2 model which includes new sword and insert. I increased the depth of the threads into the helm which adds significant strength. **

If the kids are playing in the pool or running around in the backyard, this pool noodle sword will elevate their sword game! These work with a small pool noodle with a 1” (25mm) hole. Designed to be printed helm down (sword) and threads up (insert) they easily thread together so you can get your battle time going! The pool noodle fits snugly onto the insert so it doesn’t come off during your duels! 

Printing Directions:
**Outer layers > 3
Infill > 50%**

Pool Noodle Sword - Arabian Knight

Arabian Knight.stl

So Simple and So useful 
If you like me you always have a pack of razor blades laying around, this is true for 3d printing, model making, art work, or around the shop. free to download for limited time only.
This design allows you to have more control and apply more force without hurting your fingers, with two grip styles and simple blade swopping design this is a must have for any shop!

ASA or PETG is recommended on 0.1mm layer height for best detail but any material should work fine.. ideal print for that last bit of filament left on the spool 

updated files contain slide on cover and key ring holder hole as well if needed

Below is a link to the blades I have been using with this design bought from amazon 
https://amzn.to/3TTyx5k

PLEASE NOTE, USING THIS DESIGN DOES NOT RELEASE YOU FROM BEING AN ADULT.. USE WITH CAUTION AND CARE, SHARP OBJECTS MAY HURT, AND OFFEND THE SENSITIVE 

Precision Razor Blade Handle 

Blade Sleeve-CF.stl

Blade Cover.stl

A concept of a stabbed heart. 
Also a torture challenge for your FDM printer. Are you brave enough to print it without supports? Of course this does not apply to resin printers, we provide pre-supported files for it.
