E-Flite Timber Battery Hatch

thingiverse

Have you lost or damaged your Eflite Timber battery hatch? Are you frustrated that it's not always available? Does the $15 replacement cost make you want to choke? Then try this 3D printed hatch. You decide on the strength vs weight tradeoff. I used a .4mm nozzle, .2mm layer height, 2 perimeter walls, three top layers, three bottom layers, and 5% Gyroid infill to create a hatch that weighs 24 grams including the latching tabs, which I printed at 100% infill. My hatch is strong enough, so you don't need to use more material than I used, but you might want to try printing a lighter version with only two top and bottom layers or a little less fill. You'll have to do some sanding and fitting of the forward tab and/or latch tab. Glue them in place using CA adhesive. I printed the hatch upside down. The latch tab is printed on edge, and the forward tab is printed with the aft edge down. You might want to use a brim for the small tabs, especially the latch tab, but bed adhesion isn't required for the hatch. If you like this hatch, don't buy me a cup of coffee. Buy yourself a glass of cheap whiskey and offer a toast: "Here's to good old Bob."
