Modelling I-Beams for Scratch Building 3D Design 3D print model

These designs came about after someone posted on Facebook that they were looking for designs for scratch build materials like I-Beams, H Columns, Tubing and Web Trusses.

I am looking at creating a set of designs for each type in various lengths (100mm, 200mm and 300mm), the idea is to create then most common sizes first but with the ability to add other sizes depending on feedback (Please message me). They can be trimmed to the exact length you require after printing.I personally model railways in OO Gauge which is 1/76 scale and this is the scale of these designs, but these design can be scaled up or down depending on your scale and what you model. Please contact me if you're having issues scaling and I will attempt to help you.

Depending on the items some designs might be best printed on a FDM printer but others on a Resin printer. With resin printers the length might be limited to your build area size.

For the I-Beam design the following sizes are included in 100mm, 200mm, 300mm lengthsHeight x Width x Thinkness (Real Life dimmesions first followed by 1/76 dimensions).1.2m x 0.8m x 60mm = 15.7mm x 7.9mm x 0.8mm;0.8m x 0.4m x 50mm = 10.5mm x 5.3mm x 0.7mm;0.6m x 0.3m x 45mm = 7.9mm x 3.9mm x 0.6mm;0.4m x 0.2m x 40mm = 5.3mm x 2.6mm x 0.5mm;

As per normal with my designs there is a balance between accuracy and printability, hopefully not affecting the look of the model too much.

I use AnyCubic Water Washable Resin for most of my items but use AnyCubic ABS Like Resin for anything that needs to be stronger and tougher.
