Star Trek Emergency Medkit

Update April 29 2024 - Added versions of the case parts that can be printed on 220x220 print beds. Those parts are in a separate folder in the files list. 

Happy to introduce this custom medkit case! It's fitted to hold a specific set of free 3D printed props that can be found here on Printables. It's an original model inspired by all the medkit styles seen on the shows. There's a little control panel cluster below the hypospray that was to fill space but seemed to be a good place for a distress beacon so that's what I did.

I'm eventually going to make variations of the trays so you can have more options for contents, including for engineering, science, and tactical kits. The case with all contents can stand upright to display it open too. 

Uses 6x2mm magnets for the latches and to hold the combadge. 

Handle options - there is a split handle design so you should have no trouble attaching the hinges. If you want the strength of the whole handle it's there too just needs more work to attach all the hinges at once. Use supports on the handle pins. 

Lid options - the basic lid has cutouts for the 3D printable symbol and label but requires supports that can be hard to remove, so there is also a version that has no cutouts so you can add them as decals. For those with multi material printers, there's also an MMU version so you can print the white symbol parts embedded into the lid if you have the setup for it.

Label - the 3D-printable label has finer text and may slice rough using a .4mm nozzle, so there's a second label with larger text that should print better. Use color swapping. In Prusaslicer try changing your perimeter generator between ‘classic’ and ‘Arachne’ to optimize the text. 

Latches - was going for low profile movement and this ended up working just fine to clamp two rails together to lock the case closed. They use magnets to keep the latches in place so they don't rattle and have a bonus snapping effect. 

Lid and bottom - use supports for the latch rails. When assembling, use generous amounts of glue to secure the Bottom Infill and the Trays. 

Clips - the clip files are named abbreviated by their matching tools. Refer to the diagram to match them up. They should press into place tightly so most may not need glue. They are small but work well enough to hold the tools in place. if there are clips that are a problem for you let me know but unless you are shaking it extremely hard everything should stay secure. The vial clips should be glued or they will be too  loose. 

Hinges - they clip on tight and should be strong enough but if for some reason its loose for you just use glue. Once snapped on the lid's hinges can be very hard to remove. 

Paper graphics - the outer and inner labels are provided as PDF files that should print at the correct size automatically. Use the paper label for the lids with no label cutouts.

Printing Tips

I printed the case halves at .25mm layer height using 3 perimeters, and did the latches and hinges at .2mm with 100% infill. It took about 12 hours for the bottom and 9 for the top. 
For a nice surface finish on the inner trays I set the top infill pattern to Hilbert curve. 
Take extra care when removing the supports from the lid surface, the case is relatively thin and it's easy to scratch the surface by accident. I used needle nose pliers and pinched the supports off mostly, then used a small flat screwdriver to methodically scrape the leftovers. If you can, try to optimize your supports so they aren't too difficult to remove. 

Filaments used

All PLA. The main case and all ‘gray’ parts are made from Ziro diamond silver, the med symbol is Ziro matte white, the inner trays and infill are Elegoo black, the label is Prusament gentleman's gray.
