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

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.

Bring a touch of creative magic to your Christmas tree with these 3D-printed foldable origami stars.
Each star comes in two flat versions featuring integrated fold grooves, allowing you to easily transform them into beautiful, three-dimensional ornaments.

You’ll receive both the ready-to-print G-code and the STL files, giving you full flexibility. For unique visual effects, try experimenting with different infill patterns—they create stunning textures once the star is folded.

Perfect as tree decorations, gift add-ons, or festive DIY projects.

FYI: If you want to change the size, make sure to change the x- and y-axis only(!).

Wine Stackers, 3-Bottle per Layer Version

Wine Stackers 1v00a 3-bottle end.stl

It's the _COOLEST_ coat hanger you've ever seen! The EZPZ Hanger features a quick locking system that allows you to fold the arms down to hang up clothes in a more gentle manner.

The simple gravity-powered lock automatically keeps the arms in place when opened up, and can be easily released by lifting the lock. The modular multi-part design lets you customize each hanger to your needs and aesthetic.

**_"Happy clothes, happy life!"_**

**_Printing Guidelines_**

All parts are quite simple and will generally work with your default print settings. You may want to increase wall/shell count to 3 or 4 for the arms and hook if you plan on hanging heavy garments, but I've found just 2 shells and 15% infill works well for general use. I did use 3 shells for the pins, and since they're so small you may even want to print them solid for longevity.

Print the 'Arm' part twice. Both arms are identical, just rotated (do not mirror). You can use the _'Arm_wHook'_ variation for the ability to hang clothes from straps. 

Print one set of _'Pin_A'_ and _'Pin_B'_ for the basic hanger, and four more sets if you want to attach the optional Shoulder attachments. 

The various Shoulder parts soften the ends of the hanger, which may be more gentle on delicate sweaters and heavy coats. I like _'Shoulder_Light'_ for sweaters, and _'Shoulder_Wide'_ for heavy or extra delicate garments. I've also included _'Shoulder_WideOld'_ which has the most broad radius, though clothing can sometimes get caught on the ends while releasing, hence the updated Wide version. Print two A and B parts per hanger

To assemble, first slip the Lock onto the Hanger, then connect the arms using a Pin. Optionally add the shoulder parts afterwards.
