Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.

We used Ultimaker Breakaway material for the supports with default profile settings, which are pretty much the same as standard PLA settings.
Below are link to modify the design of the enclosure, claws and LED clips to fine tune them to adjust to your printers tolerances.
The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.
Overhangs on the servo mount portion of the Leg Claw will need supports to hold up the walls. We enabled supports in Cura 3.3.1 and then set two "Support Blockers" over both tabs on the sides.
Support Blockers will not calculate any supports in the area they are placed.
The tabs have 45 degree angles, so we won't need any supports here.
To make support removal painless, we recommend using dedicated support material like PVA, Polymaker's PolySupport, or Ultimaker's Breakaway filament.
Using support material will help parts maintain dimensional accuracy and won't fuse supports into the main part.
JST and USB ports on the enclosure protrude from the case to shielded and prevent any light from reaching the sensor. Unfortunately, we'll need to add supports to hold up the flat parts of the enclosure.
