Hardware

All hardware on Guppy is stainless steel 8-32 with the exception of hardware that mounts to the vertical tubes of the frame which is 10-32 stainless steel and 10-32 eyebolts and M3 black oxide hardware which is used to mount electronics.

  • 10-32 3/8" bolts - $14.86
  • 10-32 eyebolts - 8.95∗4=8.95 * 4 = 35.8
  • Black oxide M3 hardware set - $22

Costs

It's worth noting that our documentation of costs was not well kept until about December of 2025. We've done our best to keep documentation and we've been finding the costs as we write this.

Additionally, we won't be pricing out each indivual 3D print but we will list how many spools of filament and their costs.

Hull and Frame

  • For the hull tubes, they're both 16" long, 8.25" in diameter with a wall thickness of .25"
    • The cost is per foot, so for 36" the cost is about $215
  • The baseplate stock size is 21" x 19" and .25" thick which is then milled down to approximately 18" x 20".
    • The cost for this is $150.34
  • The end caps are 8.25" in diameter and .9" thick. The stock size is 9" x 9" and 1.25" thick.
    • The cost of each end cap is 160.74,sothetotalcostofthefourendcapsis160.74, so the total cost of the four endcaps is 642.96
  • The rest of the frame is 1" x 1" sqaure tubing with a wall thickness 0.125"
    • For a total of 72" the cost is $71.60
  • The bent brackets to fix the endcaps to the baseplate are is the only 5052 aluminum parts. The pricing from sendcutsend is $17.76
  • The gussets for the frame from sendcutsend are were priced at $16.92
  • The T200 from blue robotics are 230eachandwith8onGuppythetotalcostis230 each and with 8 on Guppy the total cost is 1840
  • The triangle gusset plates are 14.52eachandwithtwoonGuppy,thetotalcostis14.52 each and with two on Guppy, the total cost is 29.04
  • The battery hull is 4" OD and .25" thickness.
    • The cost is $89.79 for two feet.
  • The endcap o-rings were $51 for 10
  • The battery hull o-rings were

Claw

  • Various claw hardware was $135.44

Torpedos

  • The cost of the nylon filament is in the section below
  • The cost of all the springs for the spring powered prototypes is approximately $18.

3D Prints

  • The motor mounts are printed from standard 3D printing resin. We purchased about 3, 1000g containers of resin each for 18totaling18 totaling 54
  • All other 3D prints are Co-PA Nylon fillament. We purchased about four rolls each for $50.
  • We purchased TPU filament for the claw which was $30

If a specific part, price, or material is not listed, it's because we found the resource in our club room from previous robosub alumni and don't know the price or material.
