This model is based on Vic Smeed’s plan originally published by Model Maker magazine back in the late 50’s. It is the 1/24th scale Vosper Rescue and Target Towing Boat (RTTB) 2754. I have made some adjustments though, based on reference photos and for ease of printing/design.
For a quick preview and to check printer size compatibility, the following are the largest dimensions from all of the pieces: Biggest Length: 220mm, Biggest Width: 240mm, Biggest Height: 263mm. (This is the mast height. Will probably need to be sliced and resin printed.)
At 1/24 scale, this model is roughly 877mm long.
Shaft tubes are designed for 5mm tubes at 1/24th scale.
I have not printed this plan personally yet, so if you run into any glaring issues please let me know and I will modify and directly send you corrected files as necessary.
