Hand Shovel

Project developed by Zmalinow Template:Status Template:Status

Abstract

This project is a hand shovel. It can also be scaled up easily into a normal shovel. This fulfills a need where people need a shovel or don't have normal access to the materials. People can also can use this if they feel that normal shoves aren't efficient enough. The design of the shovel is to be very wide to improve scoping efficiency.

Bill of Materials

Optionally, get the files from thingiverse. http://www.thingiverse.com/thing:577651

Tools needed for fabrication of the OSAT

MOST Delta RepRap or similar RepRap 3-D printer
A 2 part epoxy or other adhesive

Technical Specifications and Assembly Instructions

Print at least one shovel and one handle. Handles fit together. It is recommended to print 2 handles to allow for a nice grip room.

The shovel can take 5+ hours to print. Each handle can take 1+ hour to print.

Assembly

Expect assembly to take 1-2 hours depending on your adhesive.

Step 1 - Remove any extra plastic from the printed holes.
Step 2 - Glue pieces together
Step 3 - Use your shovel

Common Problems and Solutions

One common problem is making is inset hole to small for the handle. Make sure that you make the inset hole at least 1 mm bigger.

Cost savings

Total build cost with 2 handles - $3.80

$4.68 - $3.80 = $0.88
