Roof Rack - Tray with 4 Sides 1/10 Scale Model by pmatt1752

Mad about off road 1/10 scale model cars, so I decided to design an accessory range here is the third of many. This is a flat tray version with 4 sides. There are two fixing methods via my rail system or my conventional roof rack system. Both are ready to bolt onto your car. If you want the racks or rails, look for my roof rack or rails files. Dimensions 190mm x 130mm.
You will notice that in most of my designs I have a large flat surface. This surface is the print surface, layer 1. This large print surface area helps to maintain bed adhesion, reduce warpage and keep the print still. In my experience this is the best way to go with regards to reliable printing, I like to aim for a 99% hit rate on my prints but in reality I probably achieve about 95%.
For example the other night I was printing a large piece for my electric wheel chair project. We were at about the 2 and a half day mark and unusually, the temperature dropped quite severely during the night and to cut a long story short when I check the work that morning the PLA 300 x 300 x 400 piece about half way done had warped quite badly at the base. These types of things are very difficult to counter in the home environment. My point is that even though I had a large print surface in contact with the printer bed my object still warped! I was unlucky that time. In general the larger the print surface in contact with the bed, the more reliable the print.
These are cool but if you want a really good project to sink your teeth into, take a look at my full size electric wheel chair. Print and build a full size electric chair for under $500.
