Abstract

A few students from previous classes created smart and creative tools that could be used anywhere in the world for many different applications. I took it upon myself to create a universal, ergonomic handle, and update those tools to interchange easily with my handle.

Bill of Materials

Handle
Pin
Pruning Hook
1. (2) Stanley Heavy Duty Utility Blades (10 for $6.14)
2. (4) 3MM nuts and bolts
Cultivator Rake

Source file from FreeCAD

File:InterchangeableGardenTools.fcstd

All STLs

Tools needed for fabrication of the OSAT

MOST Delta RepRap or similar RepRap 3-D printer
Philips Screwdriver
Pliers to Tighten Nuts
Sandpaper for minor sanding to ensure perfect fits into handle

Skills and Knowledge Necessary to Make the OSAT

Slicing Software such as Cura
Open Source CAD software such as FreeCAD

Technical Specifications and Assembly Instructions

The following are the setting I used to print each piece. These may not be the optimal settings, but the final pieces work well

Handle - 32g filament - 2.5 hours to print

Infill: 10% /
Layer Height: 0.2 mm /
Shell Thickness: 1.5 mm /
Bottom and Top Thickness: 1.5 mm

Pin - 2g filament - 15 minutes to print

Infill: 10% /
Layer Height: 0.2 mm /
Shell Thickness: 1 mm /
Bottom and Top Thickness: 1 mm

Pruning Hook - Based off Hannah Power's Pruning hook - 29g filament - 2 hours to print

Infill: 50% /
Layer Height: 0.2 mm /
Shell Thickness: 1.5 mm /
Bottom and Top Thickness: 1.5 mm

Cultivator Rake - Based off Matthew Andres' Hand cultivator - 66g filament - 5 hours to print

Infill: 50% /
Layer Height: 0.2 mm /
Shell Thickness: 1.5 mm /
Bottom and Top Thickness: 1.5 mm

Common Problems and Solutions

I had an issue we parts pealing off the bed, especially the cultivator head. I printed it again with a brim and no issue

Cost savings

$3.25 in PLA filament
$1.50 in nuts and bolts from hardware store
$1.23 for 2 utility blades[1]

$4.63 Total

Commercial Equivalent

Pruning Knife - $15.74

[2]

Cultivator Rake - $10.71

[3]

Savings

$21.82
470% Savings

-Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health  care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in
+[[Category:How tos]]
