Market Day 2025 - General Stock Items 3

Challenge: To produce additional material as stock items for the 2025 School Market Day.
 

Background: We have our major school event tomorrow our School Market Day.   As we have spent considerable time explaining a number of projects the students have been developing since March this year.

We also selected certain items for sale for Market Day which we know are reliable will have an audience and we can produce relatively cheaply, although as we have noted the idea is for students to personalise items, innovation for the use of technology and creativity for the use of technology.

The badge shown above are a standard item that is easily produced by the students.   We have explained this process considerably in the past.   These prints measure 70mm long are 40mm high and currently 10mm thick.   On the Snapmaker 3D Printer these prints took one hour.

Cost: The print uses 13g of filament to produce.   For a standard roll we could produce 76 of these badges (at $30.00 per roll).  For this amount of filament and at this price the print takes 40c (rounded up) to produce and we are looking at this for setting the price.

Market Day 2025 - General Stock Items 2

Challenge: To produce a unique and original decoration suitable for Christmas.

Background: As mentioned previously we are looking for examples for items that can be used to allow purchasing during our 2025 School Market Day.  We have previously showed examples of the generic key rings that are specific to our locality.   

One of the items that we have produced in quantity in the past has been 'Christmas Themed' decorations suitable for hanging from a tree.  We have produced entire slideshows of examples of this kind of work that has been featured here on this blog during the past ten years.  You can view that slideshow here.

This new design shown left is a new example.   This was designed by a student using a combination of resources, Tinkercad was used for the design of the shape.   The image of the deer was downloaded and imported from Thingiverse.   The additional images were created using the main Tinkercad interface.

Level of Difficulty: Medium - all the elements are relatively easy to put into place and this could be completed independently within a short space of time without any input from the teacher.

Size: The print measures 100mm across and is 110mm high.  The design is only 4mm wide - however this is reflected in the purpose of the design which is to be a static print on display.

Cost: The print used 11g of filament.    Based on this we could produce 90 units with a single roll.   The cost per unit that we would need to break even with this print is $0.43c (NZD).    This could therefore determine the cost point for students.

Timeframe: 1 hour - this is completed on the Snapmaker printer.
