OSBMX 24 / OSBMX 30 Open Source Button MX 24mm and 30mm buttons

!!!WARNING!!!

I am not responsible for prints that do not turn out as intended or any damages that occur as a result of installation or usage of these buttons.

!!!WARNING!!!

If getting printed from JLCPCB, they are known for flagging issues before producing these buttons. I have re-made most of the standard files to comply with the 1.5mm minimum size for sprue rails in resin. This may still lead to an error if you are having them done in nylon PA12 or another material. I have always approved these errors and never run into any issues but please use your best judgement and think critically about what the error is they are reporting before approving. Again, I am not responsible for prints that do not turn out as intended!

!!!WARNING!!!

There are a nearly endless number of MX switches floating around out there. For the purposes of this project I focused on Cherry and Outemu switches. My personal preference was Outemu switches for this project. While you may be able to use all sorts of other switches in these, I cannot guarantee that any other switches will work. It is highly recommended to try a switch or two out to ensure proper operation before buying a ton of them.

We have a large GitHub section in OpenStick dedicated to these buttons where you can learn more about the custom PCBs that have been designed for them.  You can check that out HERE.

Summary:

The OSBMX 24 / OSBMX 30 is based on the buttons from the OFOF1 by RanaLabs (https://github.com/rana-sylvatica/OFOF1).

The OSBMX 24 / OSBMX 30 allows for a compact all-in-one button to be constructed and placed securely into a small form factor case (total of 2.00mm thick).

The OSBMX 24 / OSBMX 30 project has now been updated with an additional PCB design that takes standard 2.4mm connectors.

Please note that these buttons can also be used without the circuit board as the main housing of the button will hold the MX switches just fine. You can then use a hot swap connector directly or just solder to the MX switches. In this configuration you can also use any type of MX switch even without the notch in them.

A massive thank you to Bjart (https://twitter.com/bjartskular2) for making the original file and being great to work with throughout this project.

How to order a button housing:

All of the button housings so far have been ordered though JLCPCB. Due to the size of the buttons you can order a full sprue for a very small cost depending on the material you choose. You will get the best quality out of PA12 nylon, but they are the most expensive. If you are ordering in resin I have several larger sprue configurations in the other sprue configurations folder.

1 - Go to JLCPCB.com
2 - Click on Instant Quote
3 - Click on 3D Printing
4 - Click on Add 3D files and choose the file named OSBMX 24 - Single Sprue.stl or OSBMX 30 - Single Sprue.stl
4 - Choose the following options for the board:
 

• 3D Technology = MJF (Nylon) (1)
   
• Material = PA12-HP Nylon (2)
   
• Color = Dyed Black
   
• Build Time = 72 hours
   
• Quantity = As needed
   
• Product Description = Anything you like
   
• 3D Remarks = "Please print facing flat down."
   

5 - Click on SAVE TO CART
6 - Go through checkout process, ensure to select economic shipping to keep costs low

(1) - These are best done in MJF (Nylon). If you want to make cheaper buttons you can do them in SLA (Resin). The sprues have been optamized for ordering in MJF (Nylon). If you would like to order these in resin please check out some of the other files I have in here which have greater sized sprues. (2) - PA12-HP Nylon is recommended due to finish and feel, although it is more expensive. You can make these out of 9000R resin if you are looking to get a larger number for a lower cost, or want to experiment with doing dye jobs.
