I Am Designing A Belt Clip And Holder For My 2B Estim Control Box

Written by  May 08, 2019

If you enjoy stimming while walking around then this may be of interest to you

The 2B E-stim Control Box is an absolutely fantastic piece of equipment, and lots of people enjoy stimming while being mobile.

I decided to design my own 3D printable belt clip and holder for my 2B Control Box.

From the outset I decided on the following criteria:

  • It must be capable of holding the 2B either the right way up or upside down.
  • All sockets must be accessible.
  • You must be able to change the battery without removing the control box from the holder.
  • All controls must be accessible but also protected from accidental use when wearing it.
  • A method to control cables to keep things neat and tidy.
  • The belt clip must be able to be removed so if it ever breaks it can be replaced.
  • All outer edges must have a nice radius to prevent snagging on things.

Here is my design so far. I am waiting on some PLA arriving before I can print out a prototype. Once I have done so and then tweaked the model if it needs tweaking I will make the files available for downloading.

This means that you can get one made for yourself. I can also 3D print them for anyone, but this is a long print job.

Update: 8/5/19 - Added another cable retention and tidying option, an eyelet for use with standard cable ties.

Update: 29/9/19 - I have made the STL files for this project available.

You can download the STL files for this project here. If you find them useful then please consider making a donation to me for them to help me grow my site.

    Stoked with this new series, fantastic information and really one-of-a-kind!

    Came here for quick 3d printing suggestion: Chamfers print much better than fillets as they're limited to a 45* overhang. It'll probably end up looking nicer and work better for preventing snags on stray threads. If you use a solvent to clean up (i.e. PLA and acetone), the chamfers end up especially soft.

    @Circuit-Kink - Thank you for the suggestion and kind comments. You are right and I will probably change the design to incorporate chamfers rather than fillets. It's good to know that you like the site.

    Hi I was wondering if it is possible to get the stl file at all?
    This is exactly what I was after for my unit to protect while moving around.

    Hi Axl,
    I have made the files available in my STL downloads section of my site. The article above has been updated to show the link.

    Hi Joanne
    First of all, thanks for a very good site!

    Thanks in advance!

    Thank you for your kind words. Apologies for that, the link has been repaired and it is this one (look in the 2B Holder Folder - https://drive.google.com/drive/folders/1SxHk1O5Xr_tWs39AxKY1o-CTY-gPs00k
