Gate access keychain A23 battery

thingiverse

I've got my home territory gate access keychain. It was designed to be compact, so it used a high-capacity A27 type 12V battery that's a bit pricey and not always easy to find in my location. However, I found an even better replacement - the A23 type 12V battery with a much higher capacity, lower price point, and wider availability. It has the same length as the original but a slightly larger diameter of 10mm instead of 7mm for the A27. I created a model of the new keychain that holds the new battery type and electronics board. I also kept the red transparent window from the old design. After making the switch, the keychain works perfectly with it. The print files are ready: keychain_top and keychain_bottom. However, keychain_top requires support to print its main surface properly. While it's possible to print it without supports using PLA and a fan, I used ABS plastic without a fan, which caused the support to mix with the lower print surface and melt it deeply. To solve this issue, I added a support surface to keychain_top_surf_support. This new design still requires support but avoids melting when printed with ABS. After printing is complete, you can remove the support surface using a blunt knife, which will also open up some textured top surfaces instead of melted ones. Use keychain_top_surf_support when printing with ABS! Printer Settings: - Printer Brand: RepRap - Printer: JGAURORA Z - 605S - Rafts: No - Supports: Yes - Resolution: Layer 0.1 mm, Nozzle 0.4 mm - Infill: 100% - Notes: ABS is highly recommended for printing pocket keychains. Post-Printing: Clean the top surface (with buttons) with a blunt knife after printing keychain_top_surf_support. How I Designed This: I used OpenSCAD and probe prints to create this design.
