== Tools needed for fabrication of the OSAT==
This fruit crusher project is designed for less developed countries that do not have access to the technology that other countries have. It was designed with the use of local simple tools and scraps that would already have been acquired. It fulfills the need to crush fruit down for cooking and baking that would otherwise be a laborious task as well as a time consuming one. No previous designs have been found and commercial designs are found to be around $100.

=== Steps for Assembly ===
 
==== Step 1 ====
 
Buy necessary parts needed. See BOM for those used.
 
[[File:IMG 5380.jpg|thumb|Step 1: Lay out components (this is the hopper)]]
 
==== Step 2 ====
 
Lay out all necessary tools and components.
 
==== Step 3 ====
 
Use box base to mark hole locations on selected wood pieces.
 
==== Step 4 ====
 
Starting with a small drill bit and ending with 1/4" drill bit, drill out holes in wood. Set these aside for later.
 
==== Step 5 ====
 
Put hex bolts in mount holes with the head on the inner side of the bottom box.
 
==== Step 6 ====
 
Put washer, lock nut, washer, 5 shredder gears, washer, lock nut, washer on the threaded rod and put through the hole in the bottom box. In that order.
 
[[File:2019-12-04.jpg|thumb|Step 6: Assembly with components on one side]]
 
'''Note: Ensure that the teeth for the shredder gear face inward for both.'''
 
==== Step 7 ====
 
Put two hex nuts on the outside section of the threaded rod to use in a later step.
 
==== Step 8 ====
 
Using the 2 box end wrenches, inch the set of nuts and shredder gears so that the rod protrudes through the other side of the box base.
 
[[File:2019-12-04 (1).jpg|thumb|Step 8: Where to put wretches for ease of use]]
 
==== Step 9 ====
 
Repeat Steps 4-6 for other shredder gears.
 
==== Step 10 ====
 
Push base bottom into hopper, ensuring that the alignment is correct. This should be a tight fit. Small taps with a hammer might be necessary.
 
==== Step 11 ====
 
Put wood on 2 bolts and threaded rods on both sides.
 
==== Step 12 ====
 
Put a washer on the wood side of each bolt and threaded rod.
 
==== Step 13 ====
 
Put a lock nut next to washer on each bolt and threaded rod.


== Cost savings==
==== Step 14 ====
* If your solution is not a low cost one then it is not really appropriate.
# Estimate your costs
# Find a commercial equivalent, cite it and put the [url in square brackets]
# Calculate $ savings and % savings


== Benefited Internet Communities ==
Tighten nuts using 7/16 wretches.
* Name and add links to at least 5 using single brackets around [url name]


==References==
==== Step 15 ====


* The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <nowiki> <ref> </ref> and <references/>  </nowiki>tags and can be in any format but should include all the information necessary for someone else to find the same information you did. For example: <ref> web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html</ref>
Take earlier used hex nuts off (4 total) that were used to help tighten components.
 
==== Step 16 ====
 
Thread one lock nut per threaded rod on one side to position drive gears.
 
==== Step 17 ====
 
Put a washer, hex nut, drive gear, washer, hex nut -starting from the closest to the wood.
 
==== Step 18 ====
 
Repeat this for other threaded rod.
 
==== Step 19 ====
 
On one axel put another washer, hex nut, handle, washer, hex nut - starting from side closest to the wood.
 
==== Step 20 ====
 
Place on top of bucket
 
==== Step 21 ====
 
Insert fruit and turn handle clockwise
 
==== Step 22 ====
 
Enjoy crushed fruit!!
 
=== Print Time Estimate ===
 
19 hours - Hopper
35 minutes - each shredder gear
20 minutes - each drive gear
2 hours - Base Box
Total Print Time: 27 hours and 30 minutes
 
=== Assembly Time Estimate ===
 
1 hour
 
=== Common Problems and Solutions ===
 
* The most common problem is measuring a piece incorrectly. Just remember to measure twice and cut once.
* Other common problems were 3D prints coming out defective. This is overcome by changing the speed and temperature settings. What works for one person might not work for you. The solution to this is printing many test prints until you get your desired outcome.
* If you don't have a bucket in your location other vessels may be used. Whatever you have on hand that can act as the container to grab the fruit as it is crushed will work.
* If the 3D printed hopper is not ideal for you think about using a smaller (or larger depending on what you need) container or cup with the bottom cut out of it. The hopper is just there to direct the fruit towards the shredder gears.
* If the fruit is not getting chopped up properly or is clogging the shredder. Try cutting the fruit into smaller pieces before putting the fruit in the hopper.
* Take your time to ensure best quality work.
