This is an organizer for diabetes testing supplies, with removable bins for the consumables.  I have made efforts to make sure this model works well, and the family member who I gave it to, still uses it every day.  However, since this model is designed to hold diabetes testing supplies, I have to add that if you make or use this design, it is at your own risk.  

It includes the following design elements:

• The front left compartment is designed to hold swabs (54x25mm). 
• The large compartment is intended for a meter (53x22mm) and the one in front (left) is for a box of testing strips (20x40mm). 
• There is also a long compartment which can be used for anything else (83x27mm). 
• All the compartments are approx 37mm deep. 
• Additionally there are three places for pens which are 21mm in diameter. 
• The pen holes can be customized using some inserts, and there are 3 different diameters provided to fit different pen sizes (16.6, 18.0 and 19.7mm). The pen inserts and box lids could also be used for color coding.
• The boxes are designed to be removable so they can easily be refilled, dumped out, cleaned or replaced.

I only had a couple meters, pens and other items to check dimensions on, so hopefully the compartments will be large enough for multiple types of equipment. 

The STEP file is also available here for easy remixing.

The model is 206 x 94mm so it will fit on an X1C or P1P/P1S.

To assemble the boxes you will need the following:

• 4x M3 Brass inserts which are 4mm in diameter and 3mm long (upto 5mm may work, but will stick out a bit). -Now Optional - see note below
• 4x M3 x 20mm round head screws (this is a suggestion, you can use any size longer than 10mm) 

Note: There is now an untested insert box model (Diabetes_Testing_Caddy10C-BOX-NO-INSERTS.stl) which does not require the M3 brass inserts. It will still require the M3 screws, and maybe add some glue to keep them from working their way out. If you use the model without the inserts, please provide feedback on how it works for you. The screws will be a tight fit, but you can also heat them a bit and they may go in a bit easier.

If you use the boxes with the inserts, there should not be any heat or glue needed to install them (though you can heat set them if you want), just use one M3 screw and set them first (the inserts go in from the inside of the box). Once the inserts are seated, you can remove the screw used to set them, put the lid in place and then install the M3x20mm screws (two per box). These screws will form the hinge of the lid. The boxes can then just drop into the holes in the base.  You can color code the lids if that helps to identify what is in the boxes.

The parts are not oriented for printing but should require minimal supports. To print the lids, I suggest standing them on their thin end and using a brim to minimize the supports.

I printed it in PETG for chemical resistance since it will be wiped down with alcohol on occasion.

If you find these models useful, please post a like or a comment with some pics of your prints.

Thanks for looking!

Updates:

10/24/2020 I changed the front left side hole to be the same depth as the rest of the holes in the caddy. This should make it a bit more universal. The updated base is now named Diabetes_Testing_Caddy11-DEEP-BASE.stl. I also updated the STP and added a README.TXT which contains this description.
