The Zatarra Mark I [deprecated] - A Series of Geometric 60% Keyboard Cases

thingiverse

UPDATE (August 22, 2020): The Zatarra Mark II has replaced the original Zatarra Mark I. This series of 60% keyboard cases is designed to experiment with various tray mount styles. Variations Nos. 1-4 showcase these different mount systems. In contrast, differences among Variation Nos. 5-13 are merely cosmetic. (All latter use a ledge mount system.) Three badges can be added to the top bezel of any variation. To add a badge (or badges), you must boolean-subtract the badge mount from the case model. [The badges are re-mixed versions of models posted by others on Thingiverse. I will update this post with proper attributions as soon as possible.] Note: I have not printed out these cases yet, so cannot guarantee their feasibility or printability. However, I have printed the Haydee case (https://www.thingiverse.com/thing:4344723), which is similar to the ledge mount variations here. That print was largely successful, but was slightly small. The plate and PCB fit, but a few keycaps in the upper-left and lower-right rub against the case. Therefore, depending on your printer setup, you may need to print these cases at slightly larger than 100%. The ledge mount works as intended. Variations: - No. 1 (Ledge Mount): This variation contains a 5 mm ledge running around the inside of the tray, supporting the PCB in lieu of standoffs. - No. 2 (Standoffs): This variation includes all standard 60% PCB standoffs except the center standoff. - No. 3 (Empty Tray): This variation has no supports for the PCB; instead, it rests directly on the bottom of the tray. I recommend putting foam on the bottom of the tray if you use this version. - No. 4 (Integrated Plate): This variation incorporates an integrated plate generated by the swillkb plate and case builder. Note that this variation is split into a top half and a bottom half. I tried printing out a test plate using the swillkb builder, but the switch cutouts were slightly small. So, you may need to experiment with print size. Further, as modeled, this case will require significant supports to print out. Eventually, I plan to change the xy plane cut to align with the bottom of the plate, move the mount pegs to the bottom half, and move the mount holes to the top half, to reduce the need for supports. - No. 5 (2mm Radius Fillets on All Outside Edges): This variation uses a ledge mount system. - No. 6 (3mm Radius Fillets on All Outside Edges): This variation uses a ledge mount system. - No. 7 (4mm Radius Fillets on All Outside Edges): This variation uses a ledge mount system. - No. 8 (4mm Radius Fillets on Outside Top and Side Edges): This variation uses a ledge mount system. - No. 9 (3mm Chamfers on All Outside Edges): This variation uses a ledge mount system. - No. 10 (4mm Chamfers on Outside Top and Side Edges): This variation uses a ledge mount system. - No. 11 (Topology Optimized): This variation was created by passing Variation No. 1 through Autodesk Fusion 360's topological optimization algorithm. - No. 12 (4mm Radius Fillets on Side Edges): This variation uses a ledge mount system. - No. 13 (4mm Radius Fillets on All Outside Edges, Length Reduced): This variation is identical to No. 7, but is shorter along the x-axis by a total of 2mm. UPDATE (August 5, 2020): Added Variation No. 13.
