Folding Scalpel XL

After creating my v2.0 Folding Scalpel I received quite a few requests for it to work with the #60 blade. I originally thought it did because I was misinformed about what a #60 blade is. The number 60 blade is huge (71mm long) and simple too big for the earlier design. So I have created a hand specifically for it. And, at the same time, I made some design improvements which I have also applied to the non-XL Folding Scalpel v2.0 (which I am now calling v2.1).

This new XL model has the same basic design as the non-XL but it is effectively 11mm longer.

Besides the XL version being longer, both models of the Folding Scalpel now have improved geometry where the spring interacts above the pivot point which tightens the knife in the open and closed position. In addition, I have added a detent in the closed position. Both of these revisions are intended to help keep the knife closed when in your pocket.

Printing

I have tried to make my main print settings visible on the Cura screenshot but in case they are difficult to read I have summarized them again here…

Material: I choose to use PETG for its durability and flexibility.

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%
Ironing = ON

Screenshot

Support:
Designed to print without additional support.

Print Orientation: As shown in the screenshot(s).

Assembly Notes

No assembly or post-print processing is required. There is one piece of support that needs to be removed as shown in the accompanying illustration.

Where to Get My STL Files

Thangs.com

I am now posting all of my new designs on Thangs.com and plan to continue to do so for the foreseeable future. Some of my older designs may not have been migrated over yet so if they are not available on Thangs.com please check on Thingiverse.

Use, Licensing, Comments and Feedback

My primary distribution site for my design files is Thangs.com. Thangs.com is, in my opinion, leading the way in promoting designers and competition amongst designers which in turn fuels the growth of high-quality 3d printable designs for the benefit of our entire community. However, as a result, some of my designs are only available for free for 1 week from when first posted, so please download them when you see a new file available that you are interested in. Also, please like and save to help me with the competitions.

I do not permit the use of my designs for commercial purposes (i.e. you can not sell my design(s) or products printed from my design(s)) without first acquiring a commercial license from me. On Thangs.com I offer membership accounts for access to all my design files as well as a membership for commercial licensing which allows subscribers to sell printed products using my designs.

I welcome comments and feedback as we as requests for customization of designs. I will do my best to accommodate those requests.

    Hi, #i have just purchased this file and I cannot get my Creality Slicer to process it. As soon as I try to slice it I keep getting a “cannot open the file for writing” error.
    don you have any ideas?

      Oh, sorry to hear it. Can you tell me what website you got the file from? The exact file name? And, also if possible send me a screen shot of the message and window in your slicer. Please send me a response via my gmail address pdb6251@ gmail.com. Thank you.

      If you have not already, try downloading the file again in case that one was somehow corrupted in the download process. I assume you can slice other files ok so there must be something with that file.
