  • Leveling the Elegoo Saturn 4 build plate

    Leveling the Elegoo Saturn 4 build plate

    Tap, tap, is this thing on? I have far too many project posts languishing in the queue. Here is one. These are little washers that go on the screws of the Saturn 4 build plate in order to level it by pre-compressing the springs. The “automatic leveling” can’t adjust for lateral tilt and I’m not…

  • Printed battery cover for FrSky Taranis

    Printed battery cover for FrSky Taranis

    I normally use a LiFe 3S for the radio and my last one lasted about 10 years before puffing so bad that I couldn’t use it any more. I needed a quick replacement and wanted to use 18650 cells but they won’t fit in the stock battery compartment. Enter the 3D printer once again to…

  • 3D printed NPT Industrial to tube couplings

    3D printed NPT Industrial to tube couplings

    Various fittings to convert 1/4″ NPT Industrial Quick-Disconnect to low-pressure tubes 5/16″ and 3/16″. Both male and female tube fittings are provided. Designed based on official mil-spec MIL-C-4109F and ANSI standard B1.20.1. Shown with Tygon 5/16″ fuel tube (yellow) and 3/16″ aquarium “airline” tubing. I use these to feed air for various low-pressure applications like…

  • 3D printed tip for Apple iPad Pencil clones

    3D printed tip for Apple iPad Pencil clones

    Replacement tip for an Apple iPad Pencil 1 clone. This will not fit a real Apple Pencil as it uses a different design and it may only fit some clones, I have no idea. This one can be tricky to print because it’s so small. Use the thinnest layer height your printer can do and…

  • 3D printed feet for HP 8116A

    3D printed feet for HP 8116A

    These are OEM-style rear feet for the HP 8116A function generator. I printed the hole caps in a flexible but the original HP caps are hard plastic. Your choice. I recommend adding a modifier block to change the perimeters or infill to 100% around where the screws clamp down to provide strength. I may create…

  • 3D Printed Flux Syringe Parts

    3D Printed Flux Syringe Parts

    Sometimes I find myself with an Amtech or similar flux syringe barrel but no plunger or hub/needle so I made my own. These parts fit a 10cc barrel. The plunger and hub are printed in eSun PLA+ and the seal is eSun Elastic 83A flexible. For the flexible I used 10% infill, 1 perimeter, 2…

  • 3D Printed Ethernet Protective Sleeve/Boot and Strain Relief

    3D Printed Ethernet Protective Sleeve/Boot and Strain Relief

    When making your own Ethernet cables if it’s a cable that’s going to be moved around a lot and/or abused then it’s a good idea to protect the retainer tab and add some strain relief. This 3D printed part adds a boot or sleeve that protects the modular connector on the ends and adds cable…

  • 3D-printed 4-in-3 HDD bay

    3D-printed 4-in-3 HDD bay

    Updated version 2: Fix the drive rail part STL. This is a 4-in-3 hard drive cage with cooling fan. It fits four 3.5″ drives in to three 5.25″ slots. It can be used inside a standard PC case or on its own with no case. I often need portable drive cages for moving drives around…

  • Feit SEC3000/CAM “bricked”

    Feit SEC3000/CAM “bricked”

    Recently had to repair a bricked Fiet security camera. If too long of a WPA password is used it will cause a buffer overflow and the camera will crash which results in an endless boot-loop. There doesn’t appear to be a way to recover from this condition without getting serial access or access to the…

  • Adding a serial header to the Wyzecam V2

    Adding a serial header to the Wyzecam V2

    I have been meaning to try the open-source Intergenic bootloader for years and only just got around to it. This bootloader allows 1080p mode when using Dafang-Hacks. When messing with the bootloader it’s a good idea to have the serial connection ready for debugging or recovery so I added a header that is easy to…
