Pit box
I posted my converted tool box in the general interest forum recently, as interested in what other people are using for conveying their cars. I have also been looking at the various pit boxes used by my local club members to see what they use and the good and bad points of each plus trawling the Net for ideas of what to buy. Conclusion I came too is that if I want to replace the current box then either spend £100+ on a dedicated Pit box or spend time converting a fishing tackle box.
And now for something completely different….
A design taking ideas from various pit boxes I have seen and creating a pit box as shown below. This was printed using a Bambu P1P in sections less than 250mm cubed limit of the P1P. The MK1 design swallowed 3+ reels of filament and came in at @3.5Kg empty. Size is 350mm wide, 194 deep and 330mm high. Construction is a 4 poster bed frame of Aluminium angle to which is bolted, the boxes, and shelving. This was built up as shown to see what can be done, what is viable in print time and how thick/thin sections need to be plus some design ideas i.e. rotary catches.
Some key take aways from this is it is too heavy, the fixed internal car trays are too restrictive on access, and the internal storage is greater than my needs.
Solution is the MK2 design where the width and height are reduced, (depth is greater) and the storage reduced. This can still take up to 12 off 1/32 scale cars or 9 off 1/24 and any combination of either. The cars now sit on removable drawers, controller goes in the top drawer not a side box, and the lids/flaps are now clamshell doors 60mm deep. The doors hold cleaning tape, electrical spray, tool drivers and some drawers for spares and lane marking tape rolls. Doors held closed by a sliding catch. This has shaved off 1.5kg so now 2Kg empty, so costing less, its quicker to print and more manageable to carry. Weight saving was achieved by volume reduction, combining the sub 250mm panels into panels going up to 300mm which then looses mating walls and fixings, and otherwise reduce wall section thickness compared to the MK1. The side boxes have been deleted, as well as the ally right angle sections which has reduced the screw fixings from 20 down to 10 off M5 Hex bolts & embedded nuts, and made the assembly quicker.
To achieve the MK2 design I needed a bigger footprint printer so purchased a Sovol SV08 in the Easter sale for £382, this has a 350mm cubed footprint and for the 3dp geeks is based on the Voron 2.4 design. The Voron design comes from an open source group dedicated to developing high speed printers and Sovol have licenced a design from them. The SV08 is around 15-25% faster than my Bambu P1P (which is no slouch) which benefits printing larger parts.
Total print time using Egloo PLA + Rapid for the MK2 is @35 hours equivalent to printing 7 bodyshells so not a major issue and potential to reduce this further with a larger bore nozzle and wall thickness optimisation. Cost wise on the MK2 for filament, hardware, and printing is @£40.
Onto the MK3...
