It is basically my heat gun pointed in the general direction of the the print.. propped up precariously with a couple spools of filament and a roll of masking tape.. I was sorta surprised as to how well this ghetto setup actually worked... and thinking about it, there are some definite "pros" to this arrangement...
A proper heated bed would probably work better than this arrangement, but I am going to follow my two favorite principles on this one... the KISS principle (Keep it Simple Stupid), and the 80/20 principle (20% of the effort gets 80% of the results)... Therefore I am going to build a hair dryer mount for a slightly less ghetto and hopefully 80% functional heated bed.
And since there don't seem to be a lot of instructables that really dig into the basics of such a task, I am going to include every little detail starting with the basic idea and ending with the usable object with emphasis on the design/creation of the object. While the part I am making is very niche specific, this guide is intended to be very basic/general and geared towards someone with little experience designing a part to be built with a 3D printer or other computer based tool. Think of it as a general guide using a specific example for making something real.
Step 1: Brainstorm and Design
The first thing I am going to do is get a general idea of where I want the hair dryer to be... I want it out of the way and I want it to distribute hot air as evenly across the bed as possible. Given those considerations, I came up with the following position:
It looks like the head of my heat gun is about 66mm... If I am going to make a mount for it, I will need a little extra width for the meat of the mount... I'd say 10mm (5mm on each side) would be good enough... therefore I will allocate 76mm for the width of the center section.
... but I am hopefully not going to use my heat gun... I have a cheesy $10 Walmart hair dryer that I am going to try.. so now I will measure how big the center section mount opening needs to be...
