    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 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

    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…

  • SD memory card register decoder

    SD memory card register decoder

    This is a utility for decoding SD card registers. On Linux if you have a MMC type card reader (not USB) then you can get the register values with a command similar to: Replace X with the number of your device (use lsblk). That will return the CID and CSD respectively. The CID contains identification…
