Each one of my prototypes will be proceeded by a scale drawing. They are free to download and if needed, make whatever modifications you wish to them. Just let me know what modifications you might have made and the end result of those modifications please.
If you want to have your concept drawn, I’ll be happy to do it for you. The first hour is free and most probably wouldn’t take more than an hour to draw at full or half scale. If it take more than an hour, I charge $35.00 per hour. Simple as that. Just contact me via email with what you’re wanting. Make sure to send your notes and sketches.
